In regards to my comment I want to reference Craig’s image to illustrate the point.

In it you see how the river is integrated with its surroundings. In the upper areas the river slowly emerges from the forest. In the lower section the forest is still along the banks and the rocks continue from the upper half deep into the lower half. This composition integrates both sections to form a strong unit. I feel that this is what’s missing in your comp and it’s something I would pay attention to in the future.
