At first I thought the BG too busy but then you placed the subject very well against it.
I like the overall feel and look, I like the colors, although I can't decide if there's magenta cast
or not?
The exposure looks good to me and the bird is sharp. The abrupt change form light to green is mildly distracting to me but I do like the sense of habitat.
I really like the soft look of this. I also like the transition of the BG colors. I think it needs a slight CW rotation to minimize the difference in the far shoreline relative to the level front one. I'd also give just the bird a tweak of contrast and reduce the cyan of the BG water a bit.
