Begin layering colors to create the texture of the grass and the details of the horses and figures.

Use short, broken brushstrokes to suggest movement and light.

Refine the details of the figures and horses, paying attention to their anatomy and posture.

Add highlights to the horses and figures to create a sense of depth and dimension.
