grayscale and aerial view photography of waterfall

While waiting for the park to open during a fall day, I was playing with the settings in manual focus. Once open I went right for Cascade falls. I set up my camera and took a few photos. I was one of the only people in the park because it was a week day. Then less than an hour into shooting, I realized that the entire time my camera was still in manual focus so all my previous photos were out of focused. I calmed down after a few minutes and decided to redo my favorite shot which was this one. I noticed that the leaves were rotating beneath the falls and thought to do a long exposure.
