I rarely take the time to comment on photos that are already this popular, but this composition is exceptionally striking and I feel like it warrants a second or two of my time to tell you that this is one of the best shots I've seen hit the front page in a while Fantastic work!
Wow, Ian. Very impressive. =] The water is aggressive in a kind of passive way....if that makes any sense... Regardless; this is awesome. I love that higher up the waterfall is slightly off centre for the most part, too.
