I am really glad you like it, but actually, this Spinosaurus in my gallery is quite inaccurate... and I noticed it only now. 

When I drew it, I was inspired by Cau's interesting ideas, but I completely misunderstood them... I am a real idiot.
In fact, what he meant by "pelican-like pose" was not that the animal could facultatively keep its neck in this position, but there would have been muscles and ligaments that connected the neck directly to the sail... no like in my drawing, but more like these amazing restorations here:

Yeah, I badly need to draw a new, more accurate version of this. I think I'm going to do it in the next few days.

Mark Witton is one of my favourite exponents in paleoart\paleontology. His illustrations are amazing. The Spinosaurus reconstruction in your link is a masterpiece, but it does not represent the 2014 discoveries. As Witton wrote in the caption under the drawing, "this depiction shows Spinosaurus aegyptiacus as generally imagined prior to 2014".

Probably yes  
Since Hibraim's specimen and Stromer's "Spinosaurus B" have exactly the same proportions, the new spinosaurus is quite certainly the most correct one. How would it have walked on land? I have some ideas about that:
1) Spinosaurus spent all its life in water, and came on land only to lay eggs, crawling on its belly
2) As suggested by Andrea Cau, from who I took ispiration for this reconstruction, Spinosaurus could balance its body weight by keeping its neck in this position
3) Extremely specialized and super-developed shoulder and arm muscles (and bones) allowed him to walk as a quadrupedal animal like in Hibraim's reconstruction

Okay than

Well; I am not sure. As the Stromer deemed the fossil is different 'enough' to belong into another theropod species; and there's the sigilmassasaurus thing I recently commented about;

I would pick absolutely the 'S curved neck'-'Pelican' one the 2nd; if the reconstruction is accurate; because all the marshlands, swamps and Delta's; spinosaurus habitat; has seasonal (very harsh) droughts and as far as I know the spinosaurus can't go to open waters, ocean because it would be absolutely defenseless. And as you said the animal has to laid eggs (a new discover about a viviparous dinosaur would be immense thought) and has to protect its nest & hatchlings against predators; as currently known theropods accepted as 'good parents' by all paleontology genre... And the males have to impress females as how modern avians do. They have to do their rituals on land.
[(however how much I personally have my own theory about 'precocial'-''super precocial'' infant dinosaurs; completely capable of looking themselves; or have to look themselves.)]

However; I am definitely see the Quedrupedality as a 'wrong' theory because the animal's claws are completely not suited for a perfect quedrupedal locomotion. The animals arms so far; seemingly can't support the animal on land-aren't designed for a walking so far.
If you want to compare; compare spinosaurus 'claws' into gorilla 'arms'

Spinosaurus :

The spinosaurus arms are advanced but definitely not suited for a 'knuckle walking' gorilla type of locomotion.

The ''Pelican'' is the best answer so far to explain spinosaurus by both its behaviore & locomotion; IF the national geographic's reconsteuction is accurate.

National Geographic is definitely not a very reliable source. Check out their 'dinosaur' shows

Almost all of them is about Tyrannosaurus...

Still more watchable than obvious documentary channels; or so called documentary channels :9
