Improvment, but still has the problems Delgneith explained.
heavily edit:
Basically your colorchoices have many midtone shades and one higlightshade resultating in too much contrast.
Also some anatomically issues.
I see many randomly placed pixels, esp. on his left arm. Maybe you dont now how to shade difficulty parts
and stuff it up with some pixels in hope it looks right in the end.
Oh and lighning issues as ilustrated above.
