Very lovely composition! Love the soft light and tones. Only thing I'm not sure about is the object to the right of the person. I find it keeps drawing my eye away from the boat and the person.
Wonderful compositional triangle! Your bum must be wet as your footprints have been washed away :) There could be more in post processing, perhaps some extra contrast and saturation, however the image as such conveys a perfect photographic rule. 7.
