Hi Petri- Love the action here, and with puffins, it's quick action even a landing like this. The sidelight/backlight is compelling, especially the light through the wing. However, on my calibrated monitor, the shadow areas are quite dark and I would recommend brightening them up. Also I think the crop is a little tight on the subject although I like the way the subject is placed in the frame.
A side-lit Puffin is a challenging exposure, and you've done pretty well here. I like the sense of cliff habitat and the OOF water below. I do agree with John that a looser crop would improve things, and I wish the wing on the right side of the image was in better position. Happy to see you continuing to post!
Very nice and dynamic shot. I just wish the specular highlights aroung the feet were not there. I find them a bit distracting.
I like the sense of motion the picture evokes.
