If you took it in RAW, try doing an HDR with a single RAW, by taking out 3 JPG's (one under, this one, and one over exposed). It should make the trees pop a little more. Just turn the sliders down to make it look a bit more natural and not so overcooked. Also, place the horizon (water's edge) at the lower third; should help a bit with composition and show more of the sky, which I think is the real subject here. This is just what I would do here (not necesarily what is right).
