basic "model sheet-style lineart for big cat species
available at : https://maim.itch.io/bigcat-ref

these are just flat PNGs, so they'll work with whatever art program you'd normally use (or you could even print it out and color it by hand)
I'll probably add some more variants if it does well
I've got a few templates/lineart things I need to finish first, but I'm planning on doing canines and small cats in a similar style soon-ish
