I heard my professor, Brian Hoover, say it 101 times and my own students hear me say it over and over again. There are only two things that can go wrong with a painting - shape and color. So the first thing I'm working on is creating a shape that will work. As I said, I am working from several different, very poor and very old references. If I were trying to create a generic person it would be one thing. But this is actually supposed to look like a particular person when I'm finished. So I have to be really careful about getting it right from the start.
