Sat in on a life drawing class. The first one is the model. After a few of these, I started in on the students. Just as much fun. Artists out there..... draw from life. Reference is good. You learn to keep your vocabulary open and the work is more realistic. But it does become just drawings of photos of people as opposed to drawing OF people. You need to draw from life. It's more intimate, it requires more intuition. It makes you pay attention more and learn more about weight and form. I don't do it enough, but this was a good kick in the arse about it.
