Who is next pony? (Patreon)

We're getting closer to a public release, and after that, I want to put together the next character rig. BB (artist) and I have a pretty good idea of what the poses and scenes will look like, and we've decided to do them in order of technical complexity. 

But I could still use some input on the exact order-

• Should the next character be AJ or Fluttershy?
• After those two, it'll be Twilight and Pinkie. Which should come first?
• Dash is last. She's the hardest. :3

What do ya'll think?
