I think it is a lovely image, but ....
... the "swan at evening" is a very old and powerful symbol, and an image that carries an enormous amount of baggage. This applies especially to the Celtic tradition, in which the souls of the dead are believed to take the form of a swan as they pass to the other world, so each swan on a lake in the evening is a recently dead person. The swan has been a symbol everywhere, however - in Wagner's "Parsifal" the swan symbolises beings without consciousness but in the divine realm and Ludwig II took that up in Neuschwanstein - etc etc.
I think your image, with the picturesque element of the golden water, refers to the swan as a symbol without saying anything about it, and I think the image would be stronger if it either had some background that might extend the range of reference or was nearer a picture of a swan that clearly did not invoke traditional symbolism.
