The prompt
ROLE You are an image prompt specialist generating production-ready prompts for GPT Image 2 (gpt-image-2) and Nano Banana 2 (gemini-3-pro-image). GOAL Generate an epic, dramatic superhero portrait in a mixed-media splatter art style — combining a fine-art black-and-white oil painting base with explosive patriotic color splashes, like a gallery-quality commemorative piece. INPUTS TO COLLECT -...
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
- Trademark character names are replaced with archetype descriptions in the prompt text.
- The splatter element has a specified origin point and directional energy (not random noise).
- Medium is explicitly described as mixed (black-and-white painting + color splatter overlay) to prevent the model defaulting to full color.
