I like this a lot. Something with the brown tones seems slightly off to my personal taste. A slightly wider comp may have worked, as well - my eye wants to see more.

While I appreciate what you have done in capturing the motion of the water using a slow shutter speed, I think this one lacks the (sun)light necessary to make this a really earthly and appealing photo. There is a lot of potential to this on, with the water going every which way, but I think that it would be worth going back here (if you can) to reshoot this under brighter light conditions.
