Her name is actually spelled Cadance (ugh it looks so wrong...) even though it's Princess something something Cadenza and the word is cadence and ugh.
Anyway. Rant aside.
She's absolutely beautiful. I think you could have made the ends of the wings purple, but that's not super necessary. She's amazingly beautiful, goodness! This is even better than what I imagined for her human form.
Amaizing job! I love the beautiful blend of colors you used and the perfection you always have with shading (which i totally suck at)! You did an amaizing job with the markers, the piece almost looks digital (it took me forever to realize it wasnt) ^u^ Yet another astounding masterpiece from the endlessly talented Shugar!! <333
When I draw people with rainbow skin I don't think of it as regular human skin because that's no fun. I think of it as this smooth slick surface, like a dolphin or like hard candy so I like to portray that with the shiny-ness.
