hey
EDITED...
Yea the light source(s) are very confusing to me, hard to make sense of, and I can now see why it's marked as being pillow shaded. BUT even so I still think it has nice volume, just needs a more consistent and defined light source. NOW I think another big issue is the position of the chest, I mean the center of his chest should be lined up with the center part of the abs, at the moment I thinks its way off! I think your best bet to fix this is to reposition everything below his chest, just nudge it right ways?
Hmm, now I think the anatomy of his lower arms looks most odd to me, and also around where his sholders join his chest, but hey it's a dragon after all.
Anyhows I look forward to seeing what becomes of this.
