Nice idea Bob! I think this image has lots of potential by re-distributing the tones using some PS techniques such as luminosity masks to apply curves or levels to locally adjust key areas. As it is now, the tones just don't direct me to where I think you want the viewer to look.

The green your seeing is actually there and I did not boost saturation at all. This is in McDonald Creek on the west side of Glacier National Park during the wildfires a few years ago. Unfortunately, the fires prohibited me from working the park as I wanted because much of it was closed, in fact everything east of Logan Pass at the top of Going to the Sun Road. I made the best of it by doing these abstractions in some of the waterways to pass time. Most of the streams and lakes have lots of minerals that produce these wild colors. It was either that or some moss just under the water surface. As for the upper rock shelf, I left it to show the water coming from in between but as you pointed out, it isn't really necessary and may help the keep the viewers eye on the diagonal steak of water flowing from top right to lower left. Thanks for you thoughts.

Thanks for you comments Bob. Believe it or not all of my images have a vignette applied at the end of my workflow but perhaps not enough in this case. Will try as you say and I also think I may re-crop the image to just above the last group of rocks at the bottom and some off the left to bring the waterfall closer.

I think it's too busy, Glenn. Maybe if you really zoomed-in on one of the supports for the stairs you'd find something.

I think this is great: particularly since the whites of the eyes are natural-looking.
