Thank you, gentlemen, for the additional feedback.
David, part of what I was trying to do was to preserve some sense of that grotto behind the falls, because it was large, interesting, and a unique viewpoint. However, the waterfall was the main point of interest so I did play with a variety of crops. One of them was similar to what you are suggesting, and I had a hard time deciding between them. Attached is that alternate crop, so you folks can decide for yourselves which you prefer.
