Dan. A terrific shot! A closeup of a duck is still on my bucket list...they never seem to get close enough for me. Great FFD, HA, colours and BG. It's sharp enough for me. TFS
Very nice indeed, good action stopping shutter speed, the colours look very good, great shot.
The only suggestion I have to offer is possibly the bill is a little bright, I don't know if you make it a little less bright using luminosity or perhaps blending.
