Having done some experimentation with this technique recently, I applaud your effort - the falls is very well done - I am developing an appreciation for these shutter speeds.

However, there are large dark areas that distract from the overall impact - the eye seems drawn to the large dark space and minor cloud in the sky in addition to the darker spots in the lower part of the image. I say that having struggled with this myself with light coming from the left.

The water fall is well done though - I like the curtain effect. In my experiments with this, I have found that focusing in on one aspect of the falls, rocks or what have you gives a different perspective and a whole different impact.

Pedro, looking at the thumb, the dark sky and shadows made me think this was a moonlight time exposure. There is no focal length shown in the camera data and that would be handy to know. Woulkd it have been possible to include some more (closer)foreground details to add to the sense of depth in the image?

a nice compo albeit a bit oversharpned and over curved? ;-))

Although not possible for this photo due to the aperture in use, a slower shutter speed would give a more feathery feeling in the water.

Added detail in the surrounding elements would also improve the overall image.

Having worked alot with these water images I can say there will always be something else that could have been done to make it more appealing.

Still, overall a very entertaining image that shows very good depth.

Thanks for sharing

I like this shot a lot, but agree that the clouds are distracting. I think the water movement is great but I might be tempted to saturate the red bush a bit more to make it stand out as it draws the eye in. Overall though: a well observed and very nicely taken photograph.
