Children's Volcano Cross-Section Infographic Poster — Detailed Watercolor Scienc

Create a richly detailed, hand-drawn watercolor poster showing a volcano's internal layers and labeled geological features, designed for young learners. Use it as a Arte Conceptual 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, topic, language, style, layout, rendering instructions, and customizable subject. 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.
