Nice scene. Everything is as sharp as a needle. The rocks looks good and I particularly like the fact that you can see it is water that's flowing and not some strange mist or faom that's floating along.
I also like this image very much, the river looks like water, not like a flow of milk. I am a bit concerned that the tree is so near the center of the frame. I believe it might be a stronger by composing a bit differently. Never the less, it is a good capture.
