How to use this prompt
Mermaid coves need the water to feel magical. Glowing blue water provides the supernatural element. Shells and a waterfall give the cove texture and sound. Twilight sky unifies the cool palette. Keep the scene empty of figures to preserve mystery. The 16:9 frame lets the cove stretch horizontally, showing both shore and water.
Variations to try
- Daytime cove — bright tropical water for a travel poster
- Underwater cove — view beneath the surface with coral and fish
