Figure Drawing

Here are three out of the four figure drawings I've done so far this semester in class. (The fourth one was collaborative and sucked.) The first is from the second week of class, and the second two are from the week before last. I'll try to put up my drawings as I make them, and you all can tell me if I get any better. I wasn't supposed to shade any of these, but I got bored after shaping the form with lines. My teacher yelled at me a lot.
