Oh… um… I guess I would try to find what shape groups of Applebloom’s mane correspond with shape groups in Fleetfoot’s. Like, Applebloom’s rounded bangs can sweep back into the swept back parts of Fleetfoot’s mane.
As it is though, I’m not much one for pony into pony TFs. I can’t relate to a pony turning into another pony. Just doesn’t interest me the way human to pony TFs do.
