Beautiful painting by Zeng Hao! Green Tara - originally a Hindu goddess and later adopted by some forms of Buddhism. She is known as the mother of liberation, a protectress, an obstacle remover, and an earth mother.
This design is an example of form, but more specifically, naturalistic form. Naturalistic is when the design is derived from anything in nature, or a human figure. This particular form is a human figure, which makes it a naturalistic form.
