I'm posting this as the finish, though after studying it while writing my post, I think the left side of the painting needs just a few small strikes of sunlight into that neutral mid tone to enhance the form of the trunk. I'll let it sit a while and it will tell me what it needs. We're going back to the same location this Thursday and I plan to stay with this subject. It's a good lesson in seeing the big picture in terms of design. This is just a small section of the trunk system of this massive Banyan tree. It happens that while I've been working this evening I listened to a inspirational PBS feature on Ansel Adams who was a fantastic artist with a camera.
