Absolutely genius I'm making a game about Derpy fighting vicious muffinzombies, so your art matched exactly what I was doing. I hope you won't mind me having used this pic as temporary cover photo for Facebook and Google+ accounts of the game (but if you do, please say so, I'll remove it immediately) You can see it on [link]
I absolutely love this. Would you mind if I used this picture as the titular title picture for my incredibly nonsensical short story? I would be more than happy to credit you. I have written two other nonsensical short stories involving Derpy and muffins.
