Joe, Randy covered everything nicely. I do love the clear sharp eye and the open mouth. The clam is a very nice bonus. Beautiful BG that compliments the Gull.
Although I don't mind the shallow DOF, you had the available light to raise the ISO and stop down to get the body in focus too. Great vertical comp, and the clam is a cool addition! Very nice matching BG too. I would get rid of some of the highlights on the bill.
