Pretty nice looking waterfall. I like your presentation here. I do think I would clone out at the bottom of the shot, the one straight branch that is poking up from the bottom into the water. That really sticks out and distracts. And as an alternative crop, I think I would be tempted to try a 4:5 format, and crop up from the bottom to right above that one horizontal thin log laying across the water. I think that presents a really clean shot then.
