Jesus. I've got artist's block and writer's block. Why! I can't think about anything! I can't get any juices flowing! I can't even draw circles! How is this humanly possible!? /whine
Does anyone here have any ideas about what to draw? I am trying to get better with realism. I might take a few requests.

I'm having specific trouble with hands, feet and basically, the human body. Does anyone recommend any books for this?
