Both of these are much better executions than the one in your previous post. I think I find #2 the more interesting. The long exposure/smooth water effect in #1 doesn't quite work for me. It almost looks like a torrent of Bailey's Irish Cream coming over the falls rather than water.
I'm not sure I'd have much of a problem with that, actually, although Bailey's is a bit sweet for my taste.
