That is very pretty - as a study in evening colours it can't be faulted and the image exudes calmness.
However as this is a critique site, the one comment I would make is that the rocks in the bottom right corner do nothing for the image and indeed they draw the eye away from the main image, which for me is the interplay between the duck and the tree reflections. So I would suggest cropping just enough off the bottom to nix the rocks.
Fair comment. I didn't want to crop too much as I already had cropped all the surrounding rocks. I might try cloning as I really would like to keep the reflections.
