What a beautiful scene. I love the fog and mist and the all around atmosphere. But the photo quality seems to be a little bit low, like everything could be a bit more sharp and detailed?
Looks like you tried the unsharp mask... I'm not positive, of course....but the whole foreground remains blurry to me. The background, meanwhile, is gorgeous.
It reminds me a "Hero" movie. The same atmosphere. I would love to have a huge print of this picture on my wall. Maybe without the dam, but altogether it is absolutely breathtaking. Just commenting.
