I love the division of the colors. I wonder if there was a way you could have used a long lens and wide aperture to blur out the foreground and the background to emphasize the trees and blur out the parts that aren't as pretty.
I like the way the shadows all point to the tree, and make it even more the center of attention. I may have boosted the blacks a bit to make this even more of a silhouette.
the shadows being casted by the multiple light sources are interesting but I can't say I'm terribly fond of the photo itself. From a purely visual standpoint, It's just not something that I'm drawn to.
