Prompt
A vast underground cavern filled with giant glowing crystals in amethyst purple and ice blue, crystal columns taller than houses rising from the floor toward an unseen ceiling, their light reflected in a still dark pool, and near the bottom of the frame a tiny explorer silhouette holding up a lantern, dwarfed by the nearest crystal, soft beams of crystal light crossing the darkness above, no daylight, the crystals are the only light source, atmospheric fantasy digital painting with a sense of immense scale.

How to use this prompt
"Near the bottom of the frame" plus "tiny" is a two-part instruction and both parts are needed — DALL·E loves to promote characters toward center frame at hero size, which would delete the entire sense of scale this image exists for. "Taller than houses" gives the crystals a concrete measure; vague words like "huge" produce crystals barely above head height. The still pool doubles the crystal light for free, so keep it even when changing colors. The classic failure is DALL·E adding a bright cave mouth with daylight streaming in — the "no daylight, the crystals are the only light source" clause is already in the prompt to block it, so restate it more firmly if a sunbeam still sneaks through.
Variations to try
- Amber rework — "all crystals in warm amber and gold, the pool reflecting like liquid honey"
- Discovery moment — add "the explorer reaching toward one small cracked crystal glowing brighter than all the rest"
