Absolutely. Makes positioning the characters a whole tonne easier.
@Twiface
Not particularly. Last year we ended up going for something like a ponybooru convention in ponyville, so we might do the same but with a different city this year.
@LinuxPony
Absolutely. We had a couple of foals in last year’s collab. They’re nice because they’re short and easy to place in a collage.
@FreeMau
As long as they’re pony, transparent, and have their full body visible, you can pick any of them.
