Ah Fabulous, water and falls always a great subject so a big winner here, and you have given a long enough shutter speed to give a nice veil of water, again a great way to capture water, esp with this water it looks somewhat dirty and frozen dirt just is not appealing so great choice.
I am going to whine a bit about centering the fall, it doesn't work here cause your fall just isn't symmetrical. Your dealing with a lot of light fall off too, which I think you managed rather well. But to spruce this shot up, crop the right side off to get rid of the dead space and give the falls room to come into the photo. If you felt that left the image an odd shape, then you could crop from the top too to bring back a more traditional image framing, but still give the falls room to live.
