Hmm, not crazy fond of this shot. It's technically sound, and pleasing. I think I'm mainly put off by the horizon put straight in the middle of the frame. Usually I don't like that, especially with reflection shots.
The symmetry in the reflection is nice, but I get some tension as the trees dip off, and creates asymmetry. This image seems to be a lot about symmetery (reflections, horizon dead center). With the trees dipping off, it doesn't quite come together for me.
