Avatar Wu Jin Feng

I also decide to do an Air nomad Avatar while I'm at it.
She is to appear in the sequel to this [link] (if any.) She's known as the Sky Dancer because her bending style was honed to resemble ballet (since baguazhang is circular in style.) And yes, that is a skybison behind her. I'm hoping that in Legend of Korra, they'll show that the skybison population are starting to return.
