o_b,
I really like this one. It looks like a nice setting to get away from the hustle and bustle of the city. I think the intensity of the waterfall is more in synch with the size of the waves now. I really like the slick wet appearance of the rock wall behind the fall. That looks very natural.
It took me a while but I think I figured out what didn't look quite right at the base of the fall. The big bubbly water surface needs to be roughed up a bit. There should be numerous droplets hitting the surface around the main fall so it should not look quite so glassy smooth.
