I like the colors and textures captured here. Sharp on the head and bill. Bit more DOF might have been nice for the rest of the body. Body is angling away a bit, but HA seems pretty parallel to your sensor.
If you have it, I would perhaps give it a bit more room on the left side of the frame. There are some specular hightlights in the background that you might consider cloning out, or blurring a bit.
One thing I wish you had here is more room to play with. The reason is that the legs are too close to the edge and pointing the lens more to the left would have put the bill to close instead at the other end. If this is a crop then you can simply add more room at right, and then above and below to retain the aspect ratio. Harsh light has been dealt with as best you could, but notice the heavy shadows you still got. Beautiful duck BTW, and a very joyous title!
I agree with the cropping comments, it just feels like the duck is not far enough or too far into the frame (if that makes any sense). Harsh light, but good details on the duck.
