To critique the critic: Amateurish lighting oversights aren't proof that the artist isn't human. I concur that this is an AI generated image, but I think lighting oversights aren't proof of AI generated images *on their own.* The error has to be a mistake that a human would not have made - I can understand an artist not knowing yet that they wanted hair to be there, and having done their lighting before putting the hair on. Amateur but human mistake.

A few notes that the critic missed:
First, the shadow on the arm. The human error would have been to have the upper arm be fully illuminated. (Correct is actually that it should be entirely in shadow, but that's far from obvious)

Second, the misshapen lips. This is a normal AI mistake. Humans would have made this symmetric at least. Even with no other errors, I'd say this is a dead giveaway.

Third, the irises are significantly different sizes. The only way a human would make this error is if they drew each eye independently of each other, which I find to be deeply unlikely.

Fourth, the left breast is misshapen in a way characteristic of these particular models.

It's possible to go over the background - there's lots wrong with it - and going over it makes the post extremely long.
