How to use this prompt

The one word doing the heavy lifting is 'translucent', because without it SDXL 1.0 builds a dragon out of opaque rock and you lose the whole premise. Pair it with 'refracting inner light' and 'shafts of light splintering into rainbows through its body' so the model treats the scales as glass that transmits light rather than reflecting it off a dull surface. Shoot it low-angle: a 'dramatic low-angle wide shot' reads the dragon as colossal, which a flat eye-level view flattens. Keep the gem hoard as a supporting element, not the focus; too much 'treasure' and SDXL fills the frame with gold, and the crystal dragon loses contrast against it. Jewel-tone lighting keeps the refractions coherent.

Variations to try

  • Emerald variant: recolour the dragon to glowing green crystal in a mossy jade cavern
  • Awakening pose: open the wings and add cracks of light bursting from the seams as it stirs
