Coming out of a cave? Cool! I think you might benefit from another shot that's in a little tighter, even a vertical to emphasize the vertical nature of the falls. Kudos (and this really doesn't belong in the "Lonely Images" folder... what's wrong with these people?)!
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
Thanks Nik, unfortunately when I arrived there were a group of seniors and a photographer taking their pictures, so I had to wait, then it started raining so they took a break, I set up with an umbrella and took three photos, this one is a 7 minute exposure with a 10 stop ND, it never stopped raining, fortunately I live less than an hour away....
