Generally with birds in water a lower angle is preferred and in this case the lower the better. As others have said the water is a bit bland but if you get a low perspective this type of calm water will look like glass and give a very nice look to the shot. Also, you want to have an angle where you have a nice catchlight in the eye otherwise a black eye will look a little dead. You have a slight light in the eye but I would try for a more prominent one. I think you are off to a good start.
