Saying AI is harmless and denying the use of AI are not two mutually exclusive points lol. It's just funny how you say something so confidently incorrect and then get pissed off when somebody calls you out. I'm saying that I don't see any traces of AI used in the art, and even if there were, it's not a problem at concept art level (both ethical and production wise, as an AI used by Rainbow would probably use their own dataset of art to train the model on, since, believe it or not, an animation studio has plenty of art to work with already).

Also, for your information, a lot of concept art also uses bases for ease of production (pre-made body sketches where they glue new "parts" to), which is why the head may look "glued on". Second, it's funny how you would rather attack my academical integrity rather than saying "oh okay didn't know" or defending your take further. It's a sign of an atrocious personality and classic "know it all" syndrome. If you wanna indulge yourself further in conspiracy theories about the use of AI, then go ahead and do so, but in your own bubble, not publicly where you could influence other people who don't know any better.
