Not sure if there is a reason other than Disney being Disney, but trying to get chatgpt to generate an image "in the style of Disney" fails because of "content policy".
I'm not that invested into the questions wheter it is possible to trial-and-error until you have a prompt that generates you an image. I've already seen and reblogged 3 different blog posts about how this whole campaign is made to humilate Ghibli, but it is very striking.
