Background Design

Here's the process of me creating a background piece inspired by the spirit world in Korra the Last Avatar. Which I clearly visible in the markings on the mountains.

Next, I tried a Ghibli style background but this time I decided to push the mountains further back into the background. With some massive clouds covering half of the sky. Next, I change the hue and saturation of the drawing to fit the requirements of the spirit world.
