Ooo, I think I like this one the best (out of the ones you have posted ) Although this entire series that you've done is very cool. I love to see how much you can learn through such exercises; it gets me excited about majoring in art!
Ah, great. On top of that I'm going to be preparing for the MCATs for med. school...I better get my sleep in these next couple of days before I start, or I may never see the backs of my eyelids again.
