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
