The Monkey used is a Tibetan Macaque
The source image I used is:
The fire-spitting and mask Changing animation are typical techniques used in Sichuan opera. Sichuan is a western Chinese province neighboring Tibet.
The mini-people and monkeys are modled after those in Fool's masterpiece "In a Middle of Nowhere" I thought they were really cute and wanted to see how I could use such little people.
Happy Year of the Monkey!
