JD sketches

Some attempts at getting JD's character down, though I have to say he's turned out to be more difficult to draw than Dr. Cox. Which surprises me. I think the only one I like is 1, which is worrisome given it's the first one I did and I generally like to get BETTER, not worse, when I do pages of expressions like these.

I can draw him when he's grinning hugely. When he's not I can't quite figure him out, apparently.
