I don't see a problem with her character!

I love them myself

Sorry but what?
Dude she's by far your best OC.

I love her, and want to do more with her, personally. Doubt I'm alone. But I also feel inclined to point out that the tastes she's meant to cater to aren't exactly... the kind that everyone enjoys, y'know?
And sometimes a character's reputation precedes them so much that artists will say no by virtue of that, because "I don't want to be associated with a character that's associated with X because then people will think negative things about me nyeehhh" is... a recurring reason for a lot of alternate account separation and bipolar treatment that goes on. Just from what I've noticed over the years.

wait, did the artist tell you specifically that you weren't picked? if so, Ouch. I don't think she's a bad character at all, just keep on moving forward

No, she is not. I consider her to be one of your greatest characters.
