I made this vector based on a special cover of the Issue #16 of the Official MLP Comics. This cover design belongs to "Jetpack - Comics and Games", and their trend of pony hereos.
You can find that cover here in this [LINK]
This image is free to use since it was based from the show, though I would really appreciate if you show me where you have used. As always, please don’t use it for gore or NSFW images.
