It's been a while since I've used Ibis Paint, and yeah I did not know how well fleshed out it's perspective tools are till now. Krita I'm pretty sure I can't use images in a drawing like this, but I can here and adjust them to a one point liner perspective.

Mind you I'm not done. I still got to put another chair and a table in. But maybe give me some bipedal refs and I can see how well I can embed them over the models. Just some notes about that:

Wings are a maybe at best.
Extra arms are a maybe at best.
Tails I can probably do, unless there's a mouth there as well, that part might come out odd.
Some textiles and clothing styles might not come out right.
Simple particles I can do easily but anything more complex and there won't be a lot of them.
Anything that emits or reflects light on them normally might not be correct with my current skills.
