Gunmetal Mecha Girl Over Dark Sea-City — Sora 2 Prompt
Produce a cinematic, moody illustration of a mecha girl on a rusted platform, overlooking a submerged city—great for sci-fi concept art and visual storytelling.

Create a moody key visual of a mecha girl standing on the rusted edge of a tilted steel platform over dark water. She has pale skin, ash-white hair in a high ponytail, matte gunmetal exoskeleton armor, glowing cyan coolant lines, and a massive rail cannon on her shoulder. Behind her, a vast derelict sea-city rises from the ocean in colossal silhouettes, with fog, dead cables, rusted towers, and bruised dusk light. Use cinematic concept-art lighting and a medium-wide shot.

Produce a cinematic, moody illustration of a mecha girl on a rusted platform, overlooking a submerged city—great for sci-fi concept art and visual storytelling. 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.
Common directions include character design, advanced, mecha, and key visual. Treat these tags as creative cues; the prompt structure and preview image are the more useful guide.
