I love the stark, graphic feel of this scene. Good use of the sky. The reflection from the front tree hitting the frame bothers me a little bit, I think it better would be blurred or cloned out...
I feel the point of view is a little high. The top of the trees are at most even with eye-level, making them seem diminished and unimportant. I kind of wish I could see this from a little closer to the ground, I think it would have a bit more drama.
