Lets work our way from his feet (or lack there of) to his head, shall we? You mine as well give him feet. Don't be lazy. His calfs are looking way too bulky compared to his thighs. And his knees should be higher. His stomach could be a little larger/muscular. What is that line at the top of his stomach...? He has no wrist, and the 2nd piece of his arm is part of his hard. The colar-calavicle- bone is supposed to touch the shoulder. The ears are too far up his head. Not sure how it is on hell spawns, but on humans the bottom of the ear is near upper lip area. Top of the head could be a little more circular. But overall the most noticible things are his weird hand-arms.
