What would you all like to see in a mini-folio? (Patreon)

So for a while now I have been trying to get round to doing some mini folios. they will be about 3-5 pics each. whereas if I ever get round to a bigger portfolio it'd probably aim to be around 15.

thing is I shove so much work onto my own shoulders I haven't gotten around to it yet x_x but I will soon!

So I just want to ask ,what would you all like the theme to be? I will take suggestions.
the easiest would probably be ponies but if you wanted something else that's be cool.
it can be NSFW or clean.

I actually in the space of writing this just came up with an idea for one, so just deleted a paragraph and wrote this instead XD but hey I will be happy to take all your suggestions for whatever themes or subjects you would like to see from mini folios in the future.

Basically I do not want to simply hold back posting my pictures to release in paid downloads. that is just simply a paywall. But instead making bonus, extra pictures for the patrons and anyone else wiling to  buy them would be kewls~
