Elsa garagarza, background artist supervisor, storyboard artist, did the latest Avatar comic in Nick Magazine, all around awesome person, has done a very nice online interview. Reposting the link here. There are examples of some of her stunning bg work.
Just replace "Oompah band" with Zhao, and voila!
