Hey Dave,
I really like this image a lot. At first, when I looked at it, I was drawn by the highlights at the tops of the tree. They did not look quite natural to me the first few times I looked at them . The more I have looked though, the more I have gotten used to them though.
The composition otherwise itself is quite impressive - I have never seen a tree like it. The one thing I will suggest is that you clone out the garbage pail.
Over-all, a rather unique shot! Thanks for sharing.
James
PS d kirk, I think that the spiral marking you are seeing is a water mark...yes, Dave?
