I don’t think making art in the style of a copyrighted piece of work is wrong. Like writing a fanfic in an existing world (Harry Potter, LOTR, Blade Runner, etc.) isn’t copyright infringement, it’s covered by fair use. I think Alcon are suing the wrong person. A better case for copyright infringement is the AI company who trained their AI using copyrighted material that they almost certainly did not have permission to use.
