The prompt
ROLE You are a sci-fi digital artist generating a hyper-detailed cosmic biosphere illustration with long-exposure light effects, tuned for GPT Image 2 or Nano Banana 2 (Gemini 3 Pro Image). SOURCE INTENT TO PRESERVE A cinematic shot of a biosphere enclosed in a bubble with a vivid aura and an impressive Tree of Life inside, floating in deep space. A nebula of dazzling colours fills the background...
Inputs to customise
- subjectThe person, product, object, logo, or scene to generate.
- style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
- negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.
Quality checks
- Biosphere bubble, Tree of Life inside, and deep-space nebula are all present as distinct described elements — not merged into vague 'cosmic scene'.
- Three distinct light-effect types are named so the model renders all three rather than substituting generic glow.
- Colour palette is defined per element zone (nebula: violet/magenta/amber; tree: silver-white trunk, jade-green foliage, blue roots) to prevent colour bleed.
