The prompt
ROLE You are an image generation specialist crafting a ready-to-run prompt for GPT Image 2 or Nano Banana 2 (Gemini 3 Pro Image), tuned for print-on-demand (POD) t-shirt artwork. GOAL Generate a clean, print-ready t-shirt graphic featuring a super low-poly vector-style animal in profile view on a solid black background — no actual t-shirt garment in the image, just the isolated graphic artwork....
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
- No t-shirt garment appears in the image — graphic-only artwork specified explicitly.
- Low-poly geometric facet style is named, preventing smooth photorealistic shading.
- Solid black background and portrait 3:4 aspect ratio are stated for POD compatibility.
