I like any character that represents or is inspired by or has traits tangentially related to stars and galaxies and stuff. I especially love the colorful interpretation of those things in her design, all throughout the arms and legs, even. That's a really interesting idea and I think it works well in your style. Hope to see more of her!
Also she's a cat, so that immediately makes it better. Not that I'm biased or anything *eyes my own profile picture*
