Very nice.
Is this really 25% FF? Excellent IQ for this size crop.
I would do a bit more NR on the BG and see if you could pull a bit more detail out of some of the whites ( although 50% of the whites look good. Just the ones on the back).
I like the crop you chose.

And I thought your previous HH pelagic shot was good. This is an amazing feat. Yes to some NR, and a little Efex Detail Extractor or Topaz Detail might help the neck. Well done.
