1. Perhaps not, but I would use a graduated density in post, from bottom up to darken it and lead the eye toward the buttes. Perhaps shortening it at the very bottom as well? The horizon seems to be quite close to the center.
2. Compositionally, I wish you could move the rightmost butte a bit further to the right, to balance it better against the two "heavy" buttes close to the center.
3.Overall darkening and vignetting might help add drama (if that is what your are after)
