Love the rippled glass effect on the water, whites look good as is the sharpness, love the soft blue.....I's be inclined to crop just above your signature to remove some of the oof foreground...personal tastes maybe and possibly tone back the blue channel a fraction as the blue seems to encroach onto the wings a little...but could be just my monitor
Beautiful hunting pose, and I love the colour of the water. Nice breeding colours too. I could see this guy a bit lower in the frame, and I'd try to tame or eliminate the darker line extending from the bill to the right edge.
