Man that is some clean stuff. The only thing that i say you should fix is the size of his feet, specifically the right one, (from his point of view* even though it's angled, it still looks pretty large. Did you use a ref pic for this? it looks practically perfect!
Ha! Now that you mention it his foot is awefully swollen. This is caused by the snake bite he received. Or was it a foot tumor... I dunno. I screwed up his right hand too. Please don't look at it... Go for it lilterror.
