Generative Ai, Quality issues

Why do you have 3D rendering signed there?
Isn't this AI generation? 

@Abambo has provided some specific areas of concern. In general, the animal hair doesn't look much like animal hair. In the first image the catchlights in the eyes don't match, and the nose is malformed. In the second image the pupils are malformed and the eggs have odd shapes. In the third image there's a purple area in the iris, and the claws are messed up. In the fourth image there's an orange area in the iris, the ornaments dangling from the collar are malformed and the claws aren't properly drawn. These errors become much more apparent when you zoom in past 100% which is exactly what the Moderators do. 

Artefacts:

(there are many more).

In addition, for some pets, the eyes are not sharp. But in light of the easily to spot artefacts, that is nearly secondary.
