Lovely use of an interesting foreground which saves this from being just another 'nice' waterfall shot. I think perhaps a slightly narrower crop may help and also, on my monitor at least, there is a tone of blue to the edges of the main bodies of water which seems a little too enhanced. As I say, that's on my monitor, it could well be my fault! Don't get me wrong, they're only my personal suggestions, as it is,you have a great picture, well done.
