Today is the first day of Buttober! A friend of mine pointed out recently (Well, I -say- recently, it was more like a month ago) that the butts of my anthro characters could use a little bit of work. To that end, I'm going to practice drawing butts all this month, one a day. Today's butt is Derpy from MLP in her mail mare outfit.

If you would like to suggest a specific butt for me to draw, please leave it in the comments and I'll see about including it!
