Ignore the dev sperging at you. He's like a stressball. All you need to do is say something that criticizes him and there he'll be. I'm not surprised he broke containment again.
There was a comparison earlier that I can't find. But you are right, there's a definite trend going on here.
Take this comic here for example from 10 years ago and then compare to PE body types. Remember he also did a set 3 years ago.
For Rogue's face I say it's too elongated. Too long compared to other art he's done of her. For Kitty, could it be the flat coloring of the upper lip with no outline? Or just the way it looks in that position? Maybe too large? You're onto something for sure.

It's like he's slowly unlearning how to be an artist.
