It looks like "all of the above". Downloading it in this resolution reveals:
1) it is in focus based on surrounding features
2) the eye does have some dark "bleed" around both pupil and OD of the iris though minor
3) it does benefit from a slight bit of sharpening. not only the eye but the entire head looks a bit improved IMO
Wow! You are very good at this Barbara. Your pelicans are feasting my eyes
Superb no that is not quite right... SUPERB!
