Please oh please tell me the reasons of why you are recoloring characters. Using bases is okay, but recoloring characters is a BIG NO. Especially when you are doing it to characters from an actual show. You can get into some serious trouble. I know this isn't likely, but MLP CAN SUE YOU for doing this.
At least try to use a base, instead of recoloring. I would recommend to take these pictures down.
