Skin tone — pony colour, no need to adjust it. Clothes — Lab coat based on Sunset's, just worn open and with her cutie mark added to the crest. Simple black crop op and short jeans. Shoes inspired by the Danger Mouse character "Professor Squawkencluck" and black socks. Plus a watch, similar to Starlight's.
I updated her hair to resemble the G4 vectors of her and made the colours more vibrant. I also updated her cutie mark by using a vector, plus added eyeshadow.
