i'll be a bitch and give you some pointers...
first off, its too glossy for me.
his arm looks like that of an old man
his rope belt looks very detached from the rest
the back part of his hair looks a little odd, so does his mouth.
on his right shoulder, the shade is on the cloth instead of on the skin. actually, it could be a combination, but no shade on the skin looks odd there...
im sure you can take care of all these stuff, if you'd want to. its a matter of taste too though ^^;;
