I disagree - the tree gave the scene a "presence" that allowed me to feel part of the scene. Without the tree, the photo, although still very three dimensional, doesn't give me the same feeling. I feel like everything is "over there" rather than "right here". Also, the bridge now seems like more of a barrier than a leading line that took me from the tree on the right, across the photo, then down through the "vortex" of snow-covered trees.
That being said, it is still an exceptional photo. If I had never seen the first, the tree wouldn't be missed quite so much.
Thanks, though, for cleaning up the white spots in the black water.
