Monochrome Astronaut Helmet Sci-Fi Movie Poster Prompt

Generate a cinematic, monochrome space-survival theatrical poster with a detailed astronaut helmet, celestial body, asteroid field, and professional typography block. 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, format, style, main subject, background, text layout, and composition. 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.
