Maelstrom

I like the tree, as well as the touches of green in the water, and how your ss provides a good sense of the motion without washing out the details completely.

Bill, I like the tree from a story-telling perspective, but as a graphic element in the photo, it interrupts the flow of the image a bit.
Whether you clone or not, it's a great image. Good shutter speed, and the colors are great. I might like to see a little more on the left, there's a few places where I'd like to see just a little more of the rocks (the 3rd - 5th bumps up from the bottom, if that makes sense).

Very dynamic image, Bill.  I like the SS and the placement of the rock in the main flow being slightly off center.  I'm on the fence about the tree, but very nice with or without it.

Love the flow and dynamic of the image. The tree is not working for me. Every time I look at the image, my eye immediately glues onto the tree. Overall, a beautiful scene. 

I like both the light and the ss, Bill. You retained nice color, detail, and a sense of motion/energy in the water. The center rock is a good focal point. 

Love the textures and color in the water, Bill, and the warm tones in the rocks, that contrast so nicely with the cooler tones in the water.  Go back and forth about the fallen tree; provides context yet being so horizontal across the top of the image it becomes a bit static to me, detracting from the flow of the water.  On further thought I think I would keep it as it does help achieve what you intended, conveying the power of these falls.

I do believe that the tree is a problem because all the visual elements in this image are going up and down with the vertical frame and the tree is going side to side. If you crop off some from the bottom to make this more like a square frame it starts to look more balanced to my eye. 

Looks like a beautiful place and the framing is good here. But that tree is quite distracting.  Good opportunity to experiment with content aware fill.

A very strong image, really enjoy the rock so boldly placed.  The incongruity of the log is impactful and for me is what would make  this falls image standout from others.A solid vote to keep it.  

Image shows the power of the waterfall at Sunwapta.  Brings back many happy memories of a wonderful trip years ago.  Like your choice of shutter speed to emphasize the water's flow and the composition as well, with the branch included.  You should proudly print and frame this one.

Beautiful image, Bill. The frothy water and rocks are perfectly placed. I like the branch also, but it really draws my wye away from the main elements, so I'd personally clone it out.
Sounds like a great trip!
