These Australian shapeshifters are called the Myn-remare and they are partially inspired by the rainbow snake Julunggul, the snake Bobbi-bobbi which gave humans the boomerang as well as some weird cryptid stuff that is probably made up. Apart from this shape, which actually turned out more monitor lizard than python, they turn into humans and Australian Carpet Pythons. I came to this war shape by reading some of the crazy stuff these believers in extent theropod dinosaurs spit out, and I don't mean that birds are dinosaurs, I mean those claiming they have reports of allosaurs or velociraptors. Well I though in the World of Darkness a shape like that could easily warped into such an image and due to the rather emu-like feet the tracks would be difficult to spot.
Thankfully, due to a commentar I noticed that this pose is very similar to this one: fav.me/d5duw6g
I just wanted to make sure that this is just a coincidence. I did notz copy that figurine.
