このプロンプトについて
Generate a magical VTuber debut stream thumbnail with a starry background, cute character, and customizable typography for your live stream announcement. Use it as a コンセプトアート starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.
This prompt is organized as structured JSON with fields such as type, character, background, and layout. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.
Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
このプロンプトの使い方
- Copy the prompt and paste it into an AI image generator like Sora 2, DALL-E 3, or Midjourney.
- Choose a model that excels at anime-style art and typography generation.
- Replace placeholder arguments in curly braces (e.g., {argument name="main title" default="初配信"}) with your own text.
- Adjust the background or character description to fit your VTuber's theme if desired.
- Generate and iterate to perfect your debut thumbnail.
