I guess another issue I might have is that the glasses are too wide.

Your JC Denton is the best one I have seen. The other people dont know what they are doing. The only issue I take with your JC Denton is the mouth. It makes JC look retarded. That sort of thing fits a little better with Paul, since Paul is always a little more concerned or just shows that sort of attitude. JC always has a poker face, and that just doesnt show with yours. I would remove the mouth completely, or find a way to minimize it.
