I really like the flow of the river from foreground to midground.
How does it look when you increase focal length, place the camera a bit more to the right and rotate it a bit more to the left? Also tilt it down a bit.
Then I imagine you have a detailed view of the river, still including the canyon wall work on the right of your image, as that's a point of interest in this image I think.
I'm wondering though if there are certain features being used here which are still in alpha phase?
