I love reflections. To me, the shoreline looks a bit tilted. Nice lighting on the trees. I've not tried it, but I've read that a long exposure helps the water be a clearer mirror. Not sure that would be helpful in this case.
I feel that you were trying to capture a perfect reflection shot, given where the image is divided and the importance you've given the reflection, but that there was too much movement in the water to really capture it effectively.
