Look at the necklace. Blends into the skin. The toes on the feet are far far too long. Now look at the left arm vs the right. The foreshortening is horrific. Even if it's not AI (it is), the anatomy is just plain wrong so I'm adding the bad_anatomy tag.
Is this just another random witch hunt? Or are you purposefully trying to vandalize an artist's reputation with baseless assertions? The artist has hundreds of images, dating back years before AI was even used, all in this style and quality or better, with the odd long-toes, but this one you think is AI generated? Maybe the artist just isn't very good at drawing feet?
Since when does bad anatomy (it's not, with exception to the feet) = to AI now? You better start flagging 50% of the images on this site if that's the case.
