The prompt

ROLE You are a print-on-demand product visualization specialist crafting prompts for GPT Image 2 and Nano Banana 2 (Gemini 3 Pro Image) that generate both the graphic design and the product mockup in a single image. GOAL Generate a split-panel product visualization image: the t-shirt graphic design on the left, and a person wearing that shirt on the right — festive, colorful, print-ready quality...

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 split-panel layout explicitly assigns the flat design to the left panel and the wearing model to the right panel.
  • Individual graphic elements are named (Christmas tree, snowflakes, Santa, gift box) not summarized as 'Christmas symbols'.
  • Model description includes skin tone, hair type, expression, and secondary wardrobe (jeans) for a complete, photorealistic product mockup.
