Sunset is interesting bc we actually see her MOST in her human form. For that reason, I consider her Equestria Girls form more “canon” than the rest, if that makes sense? But also she’s an adult bc EG makes NO SENSE that they’re in a high school like THESE ARE ADULT WOMEN?? Anyways all this to say - her EG human design has vague punk/alt vibes to it which makes? So much sense? So I kept that. She IS a reformed villain after all, and she’s a little bit spunky.
I headcanon her human form to be white, with lotsa freckles to match her red hair.
