Renegadecow makes amazing My Little Pony automata. If you're going to have an artistic specialty, that's about as cool as you can get. He's already made one of Twilight Sparkle reading and Fluttershy directing her bird choir. Most recently, he's made one of Rarity sewing in her workshop while her cat Opalescence flits her tail.
Although Fluttershy is my favorite pony and I do adore the automaton that he's made of her, I hope that he makes one for Derpy. She has so much comic potential.
Speaking of which...
