A Krea 2 prompt, tested on four seeds.

Seed 22Krea 2 Turbo
The prompt
An epic fantasy oil painting of a colossal black dragon with tattered wings circling a cliffside castle during a thunderstorm, lightning illuminating its silhouette, rain lashing the towers, tiny torches glowing in the castle windows. Dramatic chiaroscuro, visible brushstrokes, deep teal and amber palette, sweeping cinematic composition seen from below.

Why it works

  • “Epic fantasy oil painting” opens the prompt, so the medium is decided before anything else, and every seed came out with visible brushstrokes.
  • “Lightning illuminating its silhouette” sets the dragon against the brightest part of the sky, which is why it reads instantly.
  • “Tiny torches glowing in the castle windows” and “deep teal and amber palette” give the warm points of light against the cold storm.

Make it yours

  • Change the medium at the start: “An epic fantasy watercolor” or “A photorealistic film still”.
  • Make it a white dragon over a snowy fortress at dawn.
  • Add a rider on the dragon’s back, or a knight on the castle wall, for a human scale.
