Tern stands out nicely against that dark BG, Danny. Exposure and sharpness look good. Impressive open beak. May be an option to tone down the whitewash on the rock a little.
I think that is the widest I've seen a Tern's bill opened in a photograph! Excellent pose, and exposure looks good on this potentially difficult colour scheme. The eye is nice and visible within the black cap. I kinda wish the orange legs were not cast in shadow, and I agree toning down the whitewash is a good option too.
Great head turn and eye contact but the most I like in this image is th eoutstanding opening of the bill. Really nice. Another vote for toning down the white areas on the rock. The bird is a bit tight on the left.
