During Dusty's interview with MandoPony, it was requested that a foal be designed for the One True Pairing, MandoFire! (That's Mando x Wild Fire).
I'm proud to present Tune Up! (Get it?! Tune as in car AND music?)
This is a super quick drawing that I did, so it's a pose I snatched from a screenshot. I'll have a better picture up later, along with her future cutie mark!
