Assignment: Draw a pony in training.
Well, I drew not one, but multiple ponies, training for the fight of their lives: a pillow fight of epic proportions that will span across all of the slumber parties in Equestria!
The grand prize? The privilege to take the Royal sisters out to lunch at the finest eatery in Canterlot. And who wouldn't want that?
EDIT: thanks to ~JasonTheHuman for catching the missing cutie mark, sometimes those things happen when you rush.
