Only a couple of them (pretty basic, though), but:
1) Canidae (weird to not have those considering there are felidae figments)
2) Corvidae (because those birds are awesome, the art for it being a species besides crows and ravens could be a nice touch)
3) maybe a dragon figment could be interesting, there's quite a few dragon companions after all (though pocos being the only not irl animal family due to their own nature to have a figment counterpart is an interesting idea)
Update: Corvidae and Canidae have been published.
Heck yeah! I'll definitely do 1 & 2 Corvidae has so many cool birds, gosh. I've already sketched some concepts, which I'll refine and publish before Tuesday.
For 3, I might not get to the dragon figment (since I'll take some time to research creating a fantasy animal family) but I'll try to release a couple of IRL lizards in the meantime. c:
