Rainbow Haired Cat Girl Illustration

I want to see a hand-drawn style illustration with very few brushstrokes, featuring a beautiful {argument name="character" default="cat-eared girl and her gentle cat-eared friend"} with {argument name="hair color" default="rainbow-colored"} hair and {argument name="background" default="midsummer fireworks"}. Can you generate a sharp digital illustration in a Midjourney-like oil painting style?
