@Guild,
yikes
I wish you hadn't indicated you're an artist. It would be easier to answer this with full honesty.
but what the heck. I don't know you so I'm going to say it.
So much art is just awful. The odds are I'd be mortified by the quality of what was created and wouldn't want to know /wouldn't want anyone else to know.
I find it hard to think of an upside to telling someone they were a muse.

I've recently seen a classic example on FB. A photographer has credited a friend of mine as being his muse. The photos are awful and she is so upset that he mentioned her publicly. She told some of us she felt like she should apologize to our community.

edit: he's a somewhat well known commercial photographer, so he's not a hack. he just should have stayed out of the more creative side
