World of Avatar Political Map (Legend of Korra)

I found countless maps of the World of Avatar floating around the Internet. But strangely no true political maps. So here's my take.
I used this map as a base: lavanyasix.deviantart.com/art/…

This map illustrates the current borders of the Nations, at the end of Book 2: Spirits and after the Southern Water Tribe claimed its independence from the North.
