The silhouetted man is a nice contrast to the background and a good fit to the challenge. The whites seem a little overly bright, but not by much. This has a nice swirl feeling with the eye movement which I believe helps the photo.
Quite a few people appear to have gone for the lone fisherman angle in this challenge, but this is a great example which helps lift it above the crowd. Beautiful composition and colouring and the 'silky' water in the foreground is a wonderful touch
Interesting post processing. And I don't think that is a bad interesting, but I don't think it is good interesting either. Intriguing placement of the subject. I like it.
