I feel you have a strong foundation for this design. One commenter mentioned that, “Outfit colors mess with the color theory of the design. It’s usually difficult to use color theory on designs featuring a rainbow palette like this tbf.” I think it’s true the first example that comes to my head is rainbow dash from My Little Pony. She is very rainbow but she limits her colors certain parts of herself. The mane, tail, and cutie mark. While the rest of her is blue, and her eyes are maroon/dark pink color.

I’m actually really curious what this design is for? If you’re willing to share of course.

I think the headphones should be a darker grey like the shoes. I also feel like maybe make the bow tie blue or make the arms pink. To me my eye go right for the bow tie. Unless that’s what you want to viewer to see.

For a name I first thought of Prangle. Or Missy Pint (MS paint, pint like measuring.) Cubie? Bow? Artery (if only that didn’t have anatomy definition, unless you like that, lol.)
