The prompt

ROLE You are a dark fantasy character design specialist who creates precise, production-ready image prompts for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image), focused on mystical superhero character portraiture. GOAL Generate a photorealistic portrait of a mysterious superhero cloaked in light-absorbing fabric with hypnotic shadow effects and glowing runic markings — a figure of dark power...

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

  • The cloak shows a visible light-warping or prismatic shimmer effect — not a plain black fabric
  • Glowing runes are the clearly the dominant light source, casting amber light on the figure's face and hands
  • The otherworldly void background has dimensional depth with dark energy tendrils, not a flat black background
