Aesthetically, this is very nice. The last cropped version improves on the layout. The image to me looks a little soft though. I don't know if it is from jpg conversion and if anything degrades the image when posted on this site, but as a landscape photo, it should be critically sharp with exception of the moving water. I'm drawn towards the falls because it is the bright point in the image, but the surrounding rocks should be razor sharp to contrast against the soft water. I would also suggest toning down the saturation a little bit as the moss seems too bright. This could be the difference from my monitor to yours, so yours it might look more natural. Anyway, this is nice scene regardless, and if you have easy access to it, I'd continue to go back to get more photos at different times of day and seasons.
