Very nice, Rick. This is definitely one of your best shots. I think this one falls a little short of being a wall-hanger for a few reasons:
1) The crop seems a bit off. My eyes detect something at the top of the falls, and I'm left wondering what it is.
2) I think the shutter speed is a tad slow. There's some great motion blur here, but at least to me, it's a little much.
3) Lack of tonal range. If you're going to do a scene like this in B&W, there needs to be a lot of contrast to help show depth and substance. This would've made an excellent HDR choice.
