[@Buddha] I've heard of the anime, but never watched it. The martial arts is still up in the air, and I was originally planning on this being a really casual thing that doesn't require [i]too[/i] much, but a plot like that would certainly spice things up. I could definitely see "gangs" forming between the zodiacs based on their rotation or fixed elements, but the poor cat would be left out. 

As for faceclaims, I don't mind which people use. I've seen people use all types of faceclaims, so unless everyone would prefer a fixed type then I don't mind. The country will probably be in either America (It seems like most people are familiar with that, but it doesn't mean the characters have to be american) or Asia, to fit with the whole idea of it being Chinese lore.
