I honestly love this so much, I'm so happy with it and I'm incredibly tempted to steal this character for myself. I may whip up a ref for her later.
This is the closest thing to a Halloween pic I've got. Enjoy. There's a blue flame version, I'll link to it if Ray decides to post that one.
[2022 Edit:] I stole her. And by "stole" I mean Ray decided to give her to me.
