I'll volunteer, although I don't have a dedicated Pony form. I am curious to see what you have in mind for this -- curious enough that I might end up drawing a Pony-form reference prior to the weekend...! We'll see...!
EDIT1: Here is the basic idea for my Pony. Still need to come up with a mark and name, however!
EDIT2: All righty, here she is -- Misty Twilight, the grouchy scholar pony!
