Don't really know if "Classic" was the right word to use for this... whatever it is, it's based on the style of the original My Little Pony cartoons, which aired during the 80s/90s. I haven't drawn a pony in years, so there's bound to be some mistakes. I also changed Derpy's cutie mark; it's supposed to be a muffin wrapped in bubble wrap. I never got why Derpy had bubbles for a cutie mark...
