My first inclination is to really like it. Which I do. But the saturation is a bit heavy-handed, and the highlights (especially in the middle of the falls) are pure white. Am I right in assuming this is an HDR? It's a touch OVER cooked for my likes, so maybe try and dial that down just a bit? And I might crop a bit off the top, so the top edge is closer to the top of the rock on the right side.
