Figure studies old and new

I went to San Jose State to sit in on a figure drawing class a few weeks back. They only wanted the do fives so there wasn't much of an opportunity to put any detail and value. The bottom two images are from that and the top ones are a little older like '05 ish. And those pages are composed of 1's to 15's I think. I need to go more often to keep it fresh. But I love Figure drawing, the study of anatomy and the human figure has always been a great passion of mine.
