No, I'm saying that 90% of IA art has the same issue, if you watch closely, you'll see that the head always feels off like i said before, like some kind of Photoshop, it's a distinctive feature IA has, at least it's what i notice every time i see IA pictures. Besides of course other defects like hands.
I go often to pixiv and everytime i see that problem i check the tags and there it is, IA-art. And no, i can say pretty sure that it is not a skill issue, if it was hand made you can notice for sure when proportions are off because someone doesn't know how to do it.
