You did a good exposure job despite the harsh light. Sharpness is great and no need to sell the image to me since I love Gannets. Love the clean whites and the great blues.
2 areas that I think will enhance the image. Add more canvas to the right side would eave more room to allow the bird to fly into the frame. The framing as is looks too tight. Tone down the highlights would really help. You could try a mask or a blend another darker conversion.
