The body is all that this has got going for it, in it's current state. the face needs some major work, i suggest studying some of the commercial sprite's face structures/techniques. the one here looks like a scribbled anime... something. The hair looks a bit too flopped on, like a mop on top of a bald guy's head. it needs a little more weight, perhaps.
The torso looks really good, however, the back looks like it might be sticking out a bit too much, maybe if you moved the arm up one pixel and to the left one pixel... Also, his index finger is humongous.
The pants look pretty good, but i think that they could be a bit thinner, especially towards where they meet the shoe.
