It would be wonderful if I could just do it right the first time. Unfortunately I just don’t see all the relationships until I’m significantly along in the process. I’ve read stories of how Michelangelo could convey movement and form with a few deft strokes. I’m no Michelangelo!
An eraser is a wonderful thing. In this case it’s just more paint. At some future time anyone so inclined might have a good time x-raying the painting to see all the stops, starts and changes. This is just the way I work. I complain about it but that’s just part of the fun.
