First impression thought was the same as Longshadow, until I downloaded. The tree trunks magically straighten. Bravo Zulu!
Even with the download, the left side of the falls seems much higher than the right. It might be the perspective, but I sometimes alter perspective so the image "looks" better. I did download and level the falls just to see what would happen. Aesthetically it looks better (to me) and the trees are not at a wonky angle.
Did you ever consider "four seasons" images of that location? NICE work.
I have thought of that for lots of the places I've been. Sadly I live 900 miles from this location. I may be able to get a summer photo this year however. :-)
