I like the composition and the green/brown/white colours very much. Somehow the image appears a little flat and I would be tempted to try a small increase n contrast to give it a bit more pop.

Very nice shot. Some quick notes. I was actually thinking what the 'blacksmith' wrote when I read his comment. I think a 4x5 crop here would work well eliminating the left side and placing the stream running into the bottom left corner. Also some post work to make it pop a bit more as the colors seem a bit flat. Otherwise though very nice photo!
