Tepid take: no you don’t have to separate the art from the artist. There are thousands of talented artists in the world. Your life won’t be lesser without Harry fucking Potter. Find something else.
@operationpuppet ok, Rowling is a special case, openly being disgusting.
Beside this ... I do love #art (and make some myself). Most often, I discover a piece of art and love it or not. I know nearly nothing about the #artist, I don't follow them in social media. Yes that's a separation of art/artist: art in the centre.
I love your puppets. I don't know anything about your character or how you drink your coffee. A bad artist character would not make the art uglier, only prevent me from buying.
