How to use this prompt
Crystal cave scenes rely on contrast between dark rock and glowing crystals. The reflecting pool doubles the glow and adds depth. Fireflies add scale and movement. The palette should be limited to two crystal colors so it feels magical rather than rainbow-like. The 16:9 frame shows the cave walls stretching into darkness.
Variations to try
- Ice cave — blue and white crystals for a frozen fantasy scene
- Treasure cave — gold crystals and coins for an adventure setting
