I just realized I never put this here.
After a while I realized the main story gimmick in The Five Forms of Kimber is derivative of Ben 10, but Kimber is much sexier than Ben, so hey, why not. It's also admittedly a Plot Tailored to the Party with the medallion animals, but that's just how these things go.
As for the animal forms themselves, at this point my catgirl fetish should be obvious. Kimber's cat form is similar to Felicia from Darkstalkers. Compare real bird anatomy to many winged people you see in fiction and you notice the wings are completely unnatural and shouldn't function. Poking around the web I found a bunch of artists trying to do better, make people wings more realistic, which I wanted as well. I found one with a particularly clever twist and promptly stole the idea for Kimber's bird form. Credit where credit is due. If you didn't pick up on it, that last costume was a miko uniform.
