I was tempted to say "yup, Woody" to protect my ego. But where's the fun in that. Not Woody this time. Hopefully with more work and a hack jobbed Photoshop wig he will be recognizable. Still a ways to go though..
The silhouette of the head is looking really low poly. Add some extra loops up there. And as everyone else has mentioned. You absolutely have to make costumes for this guy. Or at least a wig, a cigarette and a scotch glass as extra props.
