Reminds me of Pyron, from the Darkstalkers. Nice shading, but I think there's something wrong with his anatomy...
The upper body looks too big for the lower body. And the forearm (the gold one) looks too weak for the rest of the arm.
Not too sure what that light part is below the pecs.
Normally you'd have the upper muscles on the abs then a muscle between that muscle on the abs and the back muscle.
If you get me? :P
Guess you can fix it by extending the brown in between the two muscles, so then it doesn't look as bright (and stick out as much).
Nice work though.
Thought this was a fighter sprite.
