The only 10 I gave to the challenge. It has a very fairytale feel to it (Obviously) and there isn't 1 thing I can see that is wrong with this photo. Hopefully PP techniques etc will be shared with the rest of us so we can set out to do the same thing you've accomplished here. Love it!!
I think putting your little elf/hobbit character in the photo was wise, as some of the other subjectless waterfall photos in this challenge come off a bit boring. Your character adds interest and intrigue to your photo. I also like the mood that the vignetting adds to the scene.
reminds me of tales like "Lord of the rings" - which I don't like, but the shot and the processing is great. exceptional, how the foreground and background are isolated by color.
