This is something I haven't done for quite a while. While most of my artwork contains figures, they're usually invented. So, when an artist friend of mine set up some life drawing sessions, I was interested. The image below is of a fairly quick pose, less than 20 minutes, I think. Life drawing is a useful skill, in that it forces you (by which I mean me) to be analytical. And fast.
Graphite on paper, 2007, 14" x 11". The image above contains tasteful, artistic nudity. I thought I should mention that.
