I realize when I begin to caricature I can't exaggerate as much as I would like to, so it takes a couple of tries before I can really begin to play around with the shapes. Some of that has to do with understanding the shapes from the source, or a fear of drawing new shapes and resorting to shapes I know. I think that's the worst way to go about doing this kind of drawing, especially when the point is to invent new shapes. The bottom drawing is kind of a weird hybrid of realistic with some exaggeration, but not really any simplification. Still trying to find balance and contrasts, and hopefully the more I do this the better I can get at understanding these things.
