I've seen a trend of people redesigning the mane six, particularly rainbow, so I figured I'd try my hand at it. Her mane and tail feathers were done with aerodynamics in mind. I gave her the big wings since her thing is flying! The color palette swap was just because I think she'd look cooler with a darker set of colors and a contrasting mane. Her cutie mark is supposed to be a rainbow comet thing to show her speed talent :)
