achillesian: You have a valid point with the pelvis - however, in this case it looks like (in the concept art) that his leg is behind where his "resting position" would be. In my model the leg is more bent but more forward, so it seems like it's in the correct stance to me. I guess the only animal I can think of that has his leg joints up higher than his shoulders is the stegosaurus -- I know they're extinct, but I guess that counts as a real animal? :P
Highelf: Yeah, I see what you mean. I completely redid the eye, using alligator eyes as reference. I think it looks much better. I also messed with the angles in the face.
Sebeuroc: Thank you so much for that visual! I saw exactly what you were referring to. I made those changes, too.
DaveSilver: Thank you! That's great to hear.
On top of all that, I elongated the midbody because it was too short, and fixed the tail shape. Also widened his pelvis and made his belly narrower (from side to side).
Here we go:
Thanks so much for the critique! I think it gets closer all the time.
