Description
I was wondering if I could demo breast dynamics with water balloons. Although I didn't have any as a reference, I tried to logically deduct how they they would behave. I find that water balloon with a string depicts the basic idea of breast dynamics rather well. As I'm not blessed with the privilege of having breasts, my points derive from my observations. Feel free to correct me if you find that I'm completely wrong.This demo is more like an intro for possible breasts demonstration part 2. But before the real thing, it's good to know the dynamics behind the breasts.
Numerable factors affects the shape all the time: the body position, motion, clothing... to mention some. Whatever force is manipulating the breasts, the gravity always takes place in some way or another. Obviously, the size of the breasts is a significant factor: the larger they are, the more evident the manifestation of gravity is. The basic shape is pretty much like a water drop, if the breast is hanging free. Here I demonstrate rather big breasts on flat surface.
Regardless of the size, it's the shape that make breasts attractive. So when I draw breasts, I:
-Apply gravity and support (force and opposite force).
-Make them look soft and squishy, yet firm
Hopefully you find this useful

You got the point across enough with the water balloons, even if people with experience in the boob area know better. It made sense to me, nice work. If it really gets to you find materials to reference that will get a more accurate sense of textures and gel/squishy-ness or whatever.
Found this helpful even though I am not working on a nude chick.

I love it, sexy. ;D Though, water balloons with just water is less accurate than say... water balloons with water and - ....gel? Scratch that. Make it balloons filled with gel! *squishfeel* Yep, that's better. At least coming from personal experience with my own breasts, they are a bit more firm than the water balloons I used to throw at boys in the park.
Though seeing those poor balloons being thrown around and smacked with sticks in your illustration made me wince. As I was seeing them as boobs. ;n;
I'm not suggesting change the way they're depicted 'cause i'mnoprofessonalartist.
This is coming from an area of..more a feel of the boob. "FEEL OF THE BOOB." Sounds like a cult.. D;

Boobs do not work like water balloons tho. At all. For one, they are not spheres, they are semispheres. So that end result image looks like really really bad hentai, not anything approaching realistic...
I mean, I get the general idea, but BOOBS DON'T WORK LIKE THAT
👍: 0 ⏩: 1
Of course they don't. But how do you explain that to someone who don't know anything at all? "Boobs work like boobs" won't do any good either
This is just one way to approach the matter, something for the beginners to grasp on to. This tutorial is getting a bit old already, so I apologize for my inability to demonstrate this with better examples

Interesting idea, as some crossplayers in Japan actually use special water balloons to depict their breasts in Cosplay.

WHY WOULD YOU HIT A BOOB WITH A STICK LIKE IT'S A PINATA
👍: 0 ⏩: 1
I know you posted this years ago but I just happened to come across it xD
I honestly don't know why so many people think this is a fantastic tutorial O_O
First of all, it's awesome that you are actually paying close attention to factors that affect breasts such as gravity, size, and shape. But even still, the way you draw breasts is much more fantasy and imaginary than they work in real life ^_^'
You are drawing them way, WAY too large. Proportion-wise, each boob here is larger than the shape of her head/skull. This is rarely, rarely ever natural. Most men think that women's breasts are larger than they really are because we know how to use things called like push-up bras and makeup that create illusion. But once you take off the clothes you realize it's a bit different lol.
Also, breasts don't just 'mold around objects' like you've shown here. They do not flop out and lose shape when they hit a surface. Water balloons are not the best example because breasts do not simply hold liquid, they are made of dense fat tissue and skin and muscle. They are firm, and actually take a good amount of pressure to be able to mold them into different shapes.
So yeah, as a girl I figured I would give my two cents. You're a good artist, and there's no problem using these boobs in an exaggerated manga style, but it's definitely not realistic. Call it 'how to draw anime boobs' because real women are not like this.

As someone who is also a girl:
"They do not flop out and lose shape when they hit a surface. Water balloons are not the best example because breasts do not simply hold liquid, they are made of dense fat tissue and skin and muscle. They are firm, and actually take a good amount of pressure to be able to mold them into different shapes."
Those statements are only true for breasts that are smaller and firm. The size of breasts that this artist has depicted and often draws is accurate for the water balloon example. While I agree he has proportion issues (and clearly this is not an artist that focuses on utmost realism, so why bust their balls about it?) I still think that this is one of the best examples on how to draw very large breasts, especially since very large breasts are often much softer and (especially those being badgered by gravity) do mould and sit in ways that the artist has drawn. In fact, my own large breasts (I am an H cup) behave very similarly to what is depicted here.
I agree that you have an idea of how breasts work. I do not agree that you understand how all of them work and it bothers me that being female is your excuse to pretend that you do. If you request that the artist clarify that these are not "real women's boobs" then I request that you clarify you are not an expert on all shapes, sizes, and densities of breasts as clearly you lack understanding of mine.

"clearly this is not an artist that focuses on utmost realism, so why bust their balls about it?"
As long as someone is openly accepting criticism, I don't actually see anything wrong with giving it ^_^'
"I request that you clarify you are not an expert on all shapes, sizes, and densities of breasts"
I agree, of course x) I don't exactly have a Boob Ph.D I'm waving around over here lol.
"it bothers me that being female is your excuse to pretend that you do (understand how all breasts work)"
Maybe you can start by taking a few deep breaths?
If my comment was this upsetting for you, please note me so that we can talk and come to some kind of understanding
👍: 0 ⏩: 1
I'm not as upset as you seem to think I am. 
Just because someone is open to criticism does not mean bad or inaccurate criticism is helpful. If you do not know what you're talking about, do not bother talking as though words are fact.
👍: 0 ⏩: 1
I have as good enough right to talk about the topic as yourself ^_^' You can't exactly go around telling everyone to keep their mouths shut if you don't see them as 'qualified to offer their opinion'. Well, technically you can, and you are, but it's not likely anyone is going to listen to you that way.
I dunno, I mean the artist himself responded and thanked me for my opinion, so I don't see the problem?
I must have hit some kind of nerve, otherwise you wouldn't be responding to me in such a condescending way. It's ok to be upset about something, but it's not ok to lash out at other people and attack them just because you disagree.
I'm willing to accept that I might be ignorant, and I agree to disagree, but I did not deserve any your insults and personal jabs. I don't even know you ^_^'
Again, if you still don't feel like you're getting your point across you're welcome to note me, but I'd rather not spam the artist's work with more off-topic comments xP

Thanks for the slaps straight at the face xD
No really. Although it's true that this is already old and my understanding has gone trough many changes, what you say here is true. Although I may not draw breasts very realistically, I'm honestly curious how they work and people like you are extremely helpful for gaining the proper understanding. Who would know the breasts better than women themselves? Some might get butthurt from comments like yours, but I truly appreciate that you saw the effort to comment.
I tend to draw breasts large because, well, I'm not very good at drawing them yet. I'm not happy with how I draw large breasts so I want to practice them. And as a man, I can't deny the allure of larger breast xD. However, I aim to learn drawing them so that they make sense and are natural, not just because they are big. For me, exaggeration has always been good tool for finding the boundaries between beauty and plain fetishism.
With the water balloons I just wanted demonstrate the fact that breasts aren't well, air balloons
👍: 0 ⏩: 1
I didn't mean the comments to be slap, but I can be brutally honest with critique so I'm sorry for coming off as rude ^_^'
I can understand! As a girl it can be difficult learning how to male muscles. So that's something I would love for some random guy to leave a comment saying "NO. NO THIS IS WRONG, YOU'RE DOING IT WRONG" if I was off-track, and I can fix things from there. I will risk the butthurt responses if I am able to be help to the few who are on this site looking to improve xP
I do think that the exaggeration boundary can be different for guys and girls. I mean, I think there are a lot of drawings a guy would see and say "dayum that's so sexy!" where a girl would see it and think to herself "dear lord that looks so uncomfortable I don't even understand how that would work" lol. But you're right, even if the boundary might be thin I think it can be reached, and you can make sexy drawings of women that women can appreciate too x)
I would say that both water balloons and air balloons are both pretty inaccurate examples to be honest xD It's hard coming up for a good comparison though... I mean my boobs just seem like...boobs. Maybe if you just thought of them as flesh? It's much easier just relating them to skin, and fat, and muscle, since that's literally all they are. You're probably overthinking them ^_^
Just keep looking at pics of naked people, that always helps xP But real naked people! Not models or pin-ups or porno. Find something unedited x)
If you ever want a critique let me know, I'm open for boob-talk too so you can always note me. Best of luck with your art!

You didn't go overboard with it, so it's fine. Truth hurts only if the recipient can't accept his or her faults. In order to become a good artist people need to be able to humble themselves and accept the fact that they don't know everything or they could do things differently.
Male and female way of thinking and viewing things sure is very different. I believe that males rely more on their imagination when they draw women. Only the thought that the breasts are big is enough and the larger, the better. The drawing just acts as a visual cue, everything works in imagination (though the better it's drawn, the stronger the visual cues are). I also think that "larger than what's possible" scenarios simply turn them on. Women do not really appreciate that as much since they know how uncomfortable it really is. I also guess that women aren't that strongly interested in physical body like males are.
I, for one, have used hentai mangas a lot as a reference so it's no wonder if my drawings have rather male-oriented view about women. I also believe it's rather obvious that I draw hentai. I'm rather surprised how good reception I have got from women regardless, even to the point that they have shared their knowledge. I believe there is a lot of difference in opinions even between women though.
Art is rather complicated thing to explain for people that don't have the understanding. It's hard to understand concepts that are so alien from normal way of concrete thinking. Often artists exaggerate things in order to make them clear for the viewer. Soft and big breasts appear softer and bigger than they really are. Of course, too much exaggeration breaks the illusion of realism, making the viewer wonder whether the artists is honestly curious about the dynamics or just personal satisfaction. I've been drawing breasts too squishy, so it's time for me to explore the opposite
Thanks for the offer, I'll keep that in mind. Feel free to "slap" me anytime as well xD
👍: 0 ⏩: 1
That's something we both agree on then! ^_^
That's probably true, that males use their imagination much more when they draw women. And I can understand the appeal of the "larger than life" features to grab people's attention or turn them on. But of course, with this kind of style you risk going too far ^_^' You risk undermining the actual character you are drawing, since really her boobs are what the drawing is about. You're only using her body to draw people's attention. I'm sure you already realize the problems that could come with that... you have a dude artist who gives an unrealistic portrayal of women, super-high physical standards, etc etc. I think that is what concerns me most about art in this style, it's not that I don't see how it's sexy, it's just I wonder if the viewer/artist can separate fantasy from reality. Because when someone titles a piece like this "Tutorial: The Dynamics of Female Breasts" I can only assume they believe this is how they actually work lol
It doesn't surprise me that some women like your art and watch hentai x) But I also feel like there are a lot of women out there who are pretty put-off by this art style and just don't say anything. And honestly, I'm not telling you to draw one way or another. I just feel like if you are aiming to develop an art style that will appeal to both genders, you might want to study art that doesn't use such a male-oriented view, because like you said, I could totally tell that you watch hentai from this ^_^'
Thanks for taking the time to reply btw, I know I tend to write long responses Dx

You have some wonderful tutorials!
One note: I find that real water balloons are actually too elastic to simulate human skin. Honestly, I think one of the reasons that breasts are so captivating is that there are so few things in the wold that behave the same way. Their uniqueness makes us notice.
I -have- managed to find one close analogue: soap bubbles clinging to a wall. Of course, this doesn't take into account the curved surface of the body (instead of a flat wall), and bubbles merge when they touch; but they're good for a single, nude breast that's just hanging there.
Really, though, the best option is to simply go and find someone with breasts, and ask them if you can draw them - possibly a lot. There's no substitute for life drawing. For those of you who are afraid to ask: it's hardest the first time (or perhaps the first several times); but after you've worked with a model or two, it all becomes quite natural. Also, unless you're in a particularly modest part of the world, you might be surprised at how many women are willing to help out with such things.
Worst case scenario: scrape a bit of money together and hire a model from your area to pose for you. If you're short on cash, get some artistic friends together and make it a workshop. If you're struggling with anatomy, it will be worth the expense.

You're right. Breasts aren't water balloons. I just used that to explain breasts with something people likely are familiar with. Although it's not accurate, it will take you closer to the real thing
But nothing would compare with real life studies

what is about much bigger breasts? how to draw gigantic ones? ^^
is this good?
👍: 0 ⏩: 1
When the proportions become gigantic, you won't be able to make them work realistically anymore. You will need to apply the "rules" in order to achieve satisfying results. I can't do that, at least not yet, so I'm testing how large breasts I can draw without compromising the beauty of the shape and volume.
If you ask my opinion on this one, I would say this is going overboard. The breasts have become just balloons, and they are lacking true volume and mass (in other words, they appear too flat and not realistically anchored on the body).

yeah i want to draw more realistic giant ones

Sorry for the late reply on this one…
Very large breasts, if drawn realistically, have a few things to consider:
The first is the fact that breasts are basically semi-elastic bags of fat - albeit lovely ones. As Nsio has noted in the tutorial, this causes them to "squish" with gravity and other factors. The larger the breast, the more pronounced this effect becomes. Where a small breast might appear something like a cone or dome, a larger breast becomes a pear- or teardrop-shape. This is because the weight is putting tension on the skin. Tug on an elastic band, and see how it becomes narrower, and you'll see what I mean.
The second thing to consider is the curvature of the rib-cage. Breasts don't rest flat against the body, they squish in a curve-shape, following the body's contours. This causes the breasts to move apart (without a bra or other form of support) and downward. The nipples, being (more-or-lass) at the center, will point increasingly downward and outward as the breast grows. They will also flatten out, becoming less spherical as gravity takes effect and more like a rounded crescent.
This is all a bit difficult to describe in words (which is why I love Nsio's tutorials!), so I'll leave it at that for now. If you want to study abnormally large (but realistic) breasts, try Googling "gigantomastia" or "breast hypertrophy." Using medical terms is a good way to dodge the weirdo images of K-cup implants and anime anti-physics.
For a few examples, see the left-hand images ("before" photos) at the following link: www.feelbeautiful.com/gallery/… . Note how gravity both drops and flattens them, as mentioned above. Of course, if you want them to be less droopy, there are always bras, lingerie or underbust corsetry - or a pair of friendly hands. -_^

nice tutorials you've got, great explanation' examples.
since i have really good visual memory i couldn't skip this guy's study... of your tutorials on boobs:
justiraziel.deviantart.com/art…
i commented to him in a nice way, hope he will put up you as a resource for his "study". if not, it is up to you.
do not want to be annoying to both of you, but i just felt that it is no nice(though he does not state that his work is a tutorial, just a study).
surely i can be wrong and maybe he is your source... but honestly i doubt it.
plus i am annoyed his work is featured in study groups while nobody knows about your tutorials, they are least to say more informative.
anyway, good luck in drawing

Thanks
Ah, I have seen this study. I recall that this person contacted me and linked me his study. And in fact, he has mentioned my dA page in his study... although in rather small font. He writes: REFERENCES (c) Some tutorials at the net... but nsio.deviantart.com is one of the best. The illustrations at the bottom aren't mine though, I recall the originals were drawn by Pixiv artist "Houtengeki" www.pixiv.net/member.php?id=93… . I don't have the link to the source, and I don't have pixiv account so I can't browse the gallery to see whether it's in there. It would be nice of him to put the references on the description field.
But I'm fine with that. I'm only happy to see that people are using my tutorials. Copying (vs. tracing) is a good way to study, I have done that a lot myself as well, though I haven't uploaded those studies. And indeed, he claims it to be a study rather than tutorial. Check this one out: www.youtube.com/watch?v=Xzk1ij… and you will see a bit more shameless artist trying to teach how to draw breasts, with a bit too striking similarities to my breast tutorials
Thank you for your concerns, it's good to see there are people that are willing to defend fellow artists
