These are always tough to PP as their eyes are so small and difficult to see against their black plumage.
This looks to me to be a little more brown than black. Guillemots are dark chocolate brown but razorbills, like puffins, should be black. My monitor's calibrated but it's possible that it looks black on yours Mike, monitors being the fickle things that they are.
Have you tried some (very) local dodging on the eye? It'll be tough to see though as there's no catchlight.
I hope you can pull it back because it's a very characterful shot.
