Great job on this photo! I've photographed this waterfall many times, mostly in the spring (May) and I've always debated how much of the upper falls I want to include. You did an amazing job in the previous photo getting the upper falls, which I usually *don't* photograph. I love that photo. In this one though, I might concentrate solely on the lower falls -- show us the movement and neat rocks down below (similar tohttp://www.aaronmphotography.com/Places/Yosemite/12180429_dKGF7#882151620_JczyZ). Aside from composition, I think you've got everything perfect here: there's nice silkyness without clipping, there's nice blacks/color/contrast/sharpness, there's no clipping in the trees/leaves thanks to your polarizer being in the right spot -- all around, well done!
