Although this technically DNMC with all the stuff going on around the falls I have sort of a weakness for waterfall shots and will always vote a bit higher on them So for that I will give you a 7! :)
really nice shot, but I am having a hard time seeing that is minimalist, and I am pretty open minded. The photo is actually pretty busy, which in any other challenge would not be a bad thing. Sorry 4
You have the landscape portion down well. Good use of shutter speed to show the movement of the water. Nice exposure for the light, very evenly lit. I feel you missed on the minimalism. Minimalist landscapes ought to show wide open spaces and typically use negative space as a compositional tool.
