Interesting sort of symmetry going on with the shape of the ice and the shape of the duck! Nice eye. I like the cool colors. I wish you would have cropped off the black piece at the left edge. That would have also served to put the duck more into the bottom left third creating better composition.
Cool photo (pun intended!). Great job getting some reflection in there, and pretty good clarity. I wonder if it could have been even better if the bird was closer to the right or left (entering or leaving the photo).
