This is beautiful and unlike another falling water shot, the feathery nature of the long exposed water falls makes this one seems peaceful. I don't know if the spot was actually quiet enough for contemplation or not, but the photo makes it feel that way. I like the color in this. I think this is a case where B&W would loose something.
Awesome waterfall shot. Just a little pickyness... the foreground seems too busy, maybe try cropping the bottom 4th are squatting down for a different angle. Great job!
