The Human Body

My weakest point is drawing the human body. Here's an exercise I did to try and improve on that point. I'm surprised I didn't put a hole through the paper with the number of times I erased and redrew it to get the proportions somewhat close. Comment and critiques are welcome. Enjoy!

Addendum: I keep sketching in more shadows.... o.O... I'll have to upload an updated version once I've stopped picking at it, hee hee.
