I would have liked to see the camera panned a little to the left so the waterfall was not cut off quite the same way.
I also find the rock in the foreground is kind of acting like a "fence" keeping my eye from being drawn further into the picture.
I actually like that the upper/left portion is dark. Maybe it is too dark as some suggested, but you wouldn't want it drawing someone's
eye too strongly to that corner.
Very cool though! Do you know what kind of rock this is? It's very unique the way the water cut "fingers" in the rock. I've never
really seen anything quite like it.
The rock is Limestone, possibly with a bit of Shale mixed in. It's in a mountainous area, and the bedrock is probably folded on its side, so the ridges you see are softer rock or joints along the bedding planes that have been eroded by the flow of water. The photo was taken in mid-October and the river is low. In the Spring/early Summer this spot would be completely under a torrent of water. Area is immediately upstream of the Natural Bridge, Yoho National Park, British Columbia, Canada.
Here are a couple of other photos of the same location, different angles, different post-processing treatments for consideration.
Thanks for the comments to everyone so far.
