Looking for ideas: Twitter milestone (Patreon)

Right now my Twitter profile is less than 500 followers away from reaching 40k. For that occasion I would like to draw something, but I have a difficult time coming up with an idea.
So I'm looking for your suggestions on possible characters, themes, ideas, poses, etc.!

Of course an obvious choice would be to use my fursona, Night, but if you have a good idea for any of my other characters, feel free to let me know in the comments! :3
