Nicely done, but I think you could also crop this way down and emphasize the mini falls even more. The trees on the far bank and the top of the stream (upstream) would not be missed. The falls coming in on the left might be more prominent.
You can try the crop just by moving the image around in the mointor. Try sliding it up until just a small section of tree trunk is included, slide it right putting the big rock near the corner.
I find that the water, the falls and water just below the falls are the most important subjects. I like the red leaves, too, in the right corner.
