That detail is incredibe! Dimetrodons were always my favourite dinosaurs when i was a kid. I love how you sculpted the scales and wrinkles in the skin

yet still have alot to learn. i really want to progress in this medium. this imo is a good start

What medium did you use for this model? Wax? Also, cuple of suggestions on making this already awesome pict better:
Make the posture more upright. It is mamalian relative, ad more smoother skin and maybe fur, if u want XD. THe sails also don't go up all the way, they are more like the hump on a camel, but the spines partially show
STILL A FRIKIN GOOD DRAWING, DOE!!!!!!!!!!! KEEP UP DA GUD WORK!!!!!!

thank you alot for the compliment
as for what you stated. i must note that dimetrodon cannot maintain an upright posture for very long. even though it is a stem- mammal, dimetrodon as well as other Pelycosaurs forelimbs articulate in a semi sprawled gate. similarly to modern crocodilians. being low to the ground conserves energy and an upright posture uses that energy in any activity that requires it. dimetrodon can indeed high walk, but it would most likely be conservative about it similarly to smaller crocodilians.
as for integument, the majority of this dimetrodons body is actually rough skin with some scares from previous brawls, with scales i places only on the tail, legs, and underbelly. places that can be found in some modern day basal mammalian groups such as monotremes and marsupials. ( and direct evidence from several ophiacodonts specimens do conclude that scales are present in these areas). im also on the fence about fur evolving yet in Pelycosaurs evolution. although possible, i see it happening more in more advance synapsids such as therapsid
as for the sail theory, my dimetrodon sail is very thick at the base and tapers to the top. and i must inform that the "new sail" theory is massively misinterpreted. the damage sail that was examined was not pathological and not seen in other dimetrodon specimens of all species. not to mention only seven out of the total spines had this damage and is stated straight from the abstract that the spines show signs of bone regeneration you can read more here

in short, the damage vertebrae could of easily been from injuries from another dimetrodon. this doesn't necessarily debunk the new sail reconstruction, but im more partial to the idea that these were just injuries from intraspecies fighting.
