This is for the Musician Pony contest over at the Bronies group on DA.

I did one of my favorite musicians, Tom Waits, as a mule - one of his albums is titled Mule Variations, and he has a song called "Pony", so it seemed a nice fit. I know the one canon mule doesn't have a cutie mark, but since mules are donkey/horse hybrids I figured it wasn't beyond the realm of possibility.
