Well, I'll be honest here, and hope I don't hurt your feelings.
The image really doesn't do anything for me. It's more a snapshot than anything else. You've got what appears to be the main subject (pool of water with a mini-waterfall) smack-dab centered in the image. This is usually a compositional no-no. And the excessive surrounding rocks and water tend more to detract from it.
A longer lens, or simply moving closer to it, would eliminate some of those distracting elements.
