The video shows a person's hand using a red marker to color in a drawing of a mermaid on a white piece of paper. The mermaid has long flowing hair and is sitting on a rock with her tail curled around her. The person's hand moves back and forth as they color in the drawing, adding depth and dimension to the mermaid's hair and tail. The video is shot from a top-down perspective, allowing viewers to see the entire drawing and the coloring process.
