Your gull is sharp, and although I normally don't like merges of head and wing, I think the dark underside of the wing does show off his big bill well.
Your exposure is pretty close. You might have been able to get by with +2/3 of EC, which would bring up the darker areas a bit. The whites have a little room, as most measured around 232 or so at the hottest.
Shadow recovery will help some, but some noise started to creep in on the underside of the wings when using it.
To my eye, the image has a bit of a blue cast, and you could consider warming it up just a bit to taste.
