Interesting style. My main problem with it is his left (his left, not ours) arm, what's going on there? I can't seem to tell where the lightsource is, it looks almost like it's behind and to (our) right of him, but not quite. Some shadow casting would probably help make everything pop out.
That said, the textures and clothing are quite well done, keep at it!
Edit: Aha, I see it now! My suggestions on the lightsource still stay the same though.
