This is a fantastic photo. The focus and sharpness to it is amazingly done. The color compliment the contrast reasonably well too. The only thing that I can see that needs a fix up or whatever is the very top of the picture righ along the top edge, there's a slight change in the color. And also the top of the waterfall right where the water is horizantal with the trees in the background, is blurry such as the background and isn't of the same with the rest of the middleground.
I just love waterfalls your compositional shot was gorgeous,I loved everything about it. I have visited the states a few times but never been to tennessee. its mainly west coast area Las Vegas L.A. etc and have been to florida.
