I drew the main six ponies from My Little Pony: Friendship is Magic (MLP FiM) from the side in a previous deviant so this is the front sketch. I had a little extra space so I did the Cutie Mark Crusaders afterwards.
You mean use this to create something derivative? Sure! Go for it. Technically, these are just sketches from the show so you really don't even need to credit me if you don't want, though I wouldn't mind if you wanted to. Send me a link when you're done. I'd love to see it
