Okay so, we can clearly tell that AI was used in the art but what saddens me the most is that it is also used on the artists drawing as a way to make them "prettier" or "more perfect" when the art style isn't bad (on the contrary it unique)
If it was only used in the backgrounds at least, I get it's to go faster... But why "correct" the drawings of the artist with it too ? (T-T)
