Finally got an idea of how to handle Cadance, to go with the Celestia and Luna pics. The final one will be Twilight.

Obviously took some artistic license--since she apparently has actual hair, instead of a cloud floating around her head, I decided to try to go for a bit more realism there, while still having her hair mostly stay together in a mass. I also added sparklies, even tho she doesn't have them--just couldn't resist.
