First let me say that this is a very nice image. You did a great job on the highlights & midtones. The blurring of the falls is also nicely done. Everything looks nice and sharp with good lighting. The composition is good with one little exception, top just right of center you caught someones legs tho off in the backgroud they did catch my eye. I also see a bit of blow-out on the bottom of the upper falls. As I mentioned before you did a great job with the highlights & midtones but there is a lack of detail in some of the shadows. As far as the challenge & title go, it works for me. An overall lovely capture.
