Using children's coloring books as a guide Start with a basic Depiction of a friendly, youthful mermaid with long flowing hair and a shimmering tail. She's gracefully swimming near a coral reef with sun rays piercing through the water, illuminating her path. Surround her with playful dolphins, fish, and dancing seaweed. The overall scene should be magical, serene, and suitable for a children's coloring book, black and white only without color and with clear lines and defined areas for coloring.
