I got the same score, though I got the dark haired woman. I don't remember the one I missed instead.

I feel like trying to identify unedited images and AI isn't as hard, but when they're edited it gives many of the same details that AI generated ones have. Mostly it's the smoothing out of details. This could be just that the AI was trained on a dataset pulled from images available online (which are almost all edited to some extent) or just because the way it generates it makes details not quite clear. Probably a little of both.
