this is washed out and overexposed, i had some troiuble getting the details in the feathers of the white ducks without overexposure...so i went back reshot them and lowered the exposure and came out with much better results
I think I would have preferred a cropping more off the top with more of the reflection visible at the bottom. But otherwise, this is a great shot. Good luck in the challenge!
I wish I knew enought about photography to offer you some concrete suggestions here, but I don't. I know the photo looks a little cloudy and the feathers on the right side are a little blown out, but can't tell you what to do to prevent that in the future. Maybe someone with more experience can help :)
I would have like the photo more with some more contrast and color, and maybe the whole reflection of the swan, some parts of the swan look blown out...
