I love the beautiful clouds on this one. Pretty setting. My only suggestion for improvement would have been the use of the rule of thirds. I wish that the horizon line had followed more closely on the lower horizontal thirds line.
A very good image, except for one disturbing effect, which I'm not sure how to correct. To me it appears the river flows uphill, especially in the left side of the frame.
(Ah! got it....the horizon line should be the vanishing points of the water, the two places where the water merges with the hills. If you draw a line between the two points, then rotate the image until the line is parallel with the bottom of the frame, it will work. A small level on your tripod head might help.)
