This is a nice shot with the reflections. The only thing that I like to be able to see is detail in the feathers and there does not seem to be much. White birds on a darker background are among the hardest things to photograph and get the necessary detail. I am not sure if you used any exposure compensation here. but if I was shooting something like this, I would be experimenting with a +1 to a +2 EC (and in between) just to see which one is giving me the best results. You want to apply sufficient exposure compensation to push the histogram to the right without blowing out the image. I assume you are shooting raw.
