W.I.P.

what I like is that you don`t use solid colors and the outlines of the hair look pretty good, too. But for the body you could try to set some thicker outlines, especially to work out muscles and wrinkles. If not with that, you could also try to set highlights. Meaning really going from white to black. (what many people are afraid of)just look at the middle guys right shoulder: that`s a pretty good highlight, even though it looks a little misplaced. Kepp it up^^
