Rules-lawyering drama queen but not a munchkin
Heck, your inspiration can be a stain on the wall... I misunderstood your point, when you said basis I thought you meant basis as in the first sketch that brings the layout, composition and so on. Not inspiration. Though I would question a bit if AI "art" was the only inspiration -because it seems like it would be increasingly narrow and cookie cutter-.As an artist, speaking from experience, there is no universal "artistic process," every artist has their own unique process.
If an individual finds inspiration from an AI, so be it, there is nothing stopping them from using that creative process to make art.
If an artist was classically trained, so be it, but just because they learned to do it a certain way does not mean that it is the best way, or the only way of doing things.
Some artists use visual aids or other methonds that some might consider unconventional. Tim Bradstreet, a veteran of the RPG and the comics industry, uses live models for all of his pieces, using the photograph, lighting, and his own artistic process to create a work of art.
