Visually, this is one of the most stunning pieces I've ever seen. The darkening at the edges, the light at the center that draws your eyes to the tree and the green of the grass...it is gorgeous.
The little brown bush near the front is somewhat distracting - I noticed it after studying the tree for a few moments, and now it keeps drawing my eyes to that, instead of the tree, which appears to be the focus of this piece.
The angle of the light hitting the tree is unique, however, and very well done. Overall, this is a excellent piece.
