You probably could have done without using AI. Most early vn devs just use royalty free images and use the posterize filter. But instead you decided to go the route of using skeevy shortcuts.
That was the plan BUT, if you read the TOS of those royalty free image sites carefully, they state that their images may not be used for any pornographic or obscene purposes, which is why we were hesitant to use royalty free photos from shutterstock, for example.
Anyways we're replacing them for IRL pics asap =)
