Another good night at the Society of Illustrators! One of the most challenging aspects of figure drawing (for me at least) is carrying the fresh, gestural quality of the short poses over into the long poses, where I often find myself over-working. It's important to recognize when you've rendered the heck out of something, and it's time to put the pencil down and just say 'OK, this one's done'.
(in a few of these, you can see the initial 'action line' that I lay in first. This is a single line that describes the overall action/direction of the body. I build my sketch around this line)
