I haven't had any classes on drawing yet, but I'm trying to learn by myself by drawing from some of the refrence threads around here on CA.

I have done about 10 or 11 drawings so far, but I'm just drawing them from the screen. I don't really think about it or try to get something from it. My mind is blank, I look at the screen, and I look at my paper.

My question is this: What should I be thinking about? Should I even? What details should I pay attention to? What should I expect from a figure drawing class if I take one?
