I've looked at this for a few minutes and my eyes seem to get..."stuck" at the trees. I wonder how this would look if cropped differently either from the top or bottom? It looks like a beautiful place. I like the idea of using the forfront building as a frame for your photo.
This picture has alot of potential, should have left the arch complete (instead of cropping the top off) also use a slightly different angle to get more of the bridge and not that piece of concrete structure on the bottom left.
