Good downstroke flight pose. Nice detail on the near wing, which appears to be where the focus was. Perhaps a touch of selective sharpening on the head, as Ann suggests. I might have been tempted to use a low-opacity brush of light green over the whitish areas in the water.
I think this one looks very good. Beautiful color palette here and perfect down stroke on the wings. And I really like the horizontal ripples in the water and the vertical reflections on the top of the frame that make for a super interesting background. Agree with Bill re dealing with the bright white behind the bird. Otherwise very nice.
