Fly-by Mailmare

Went ahead and fixed the fact that I've never drawn Derpy before and figured she'd look cute if I drew her doing some on the job flying.
Also had internal conflicts with whether or not to shade it better to make it lineless or not, so I said screw it and did so but kept the normal lines too.
Lineless version:
