Hi Stefan, Spectacular mood and atmosphere, and a well composed photo. The pools in the foreground make it, IMO.
Two things really distract me, though; first the tilt in the horizon, which might even have been there, but looks rather off to the oblivious viewer, and secondly, the postprocessing (shadow/highlight in CS2?) which created the halo behind the tree. Not as noticeable at first, but looking more closely, it becomes visible, and starts drawing a lot of attention to it. I think with a bit more care and subtlety, this shot would really be a match for the greatest...
