Modular vehicle poster director

Act as an original mobility-concept and editorial-poster art director. Create one 4:5 vertical hero poster for {publication context}, featuring {original or authorized vehicle concept}. Inputs include vehicle name and purpose {concept brief}, defining form features {features}, body color {primary color}, accent color {accent color}, background color {background color}, one large numeral {two digits}, headline {no more than two English words}, small subhead {no more than four English words}, and desired character {precise, agile, durable, or futuristic}. Use only original designs or references the user has the right to use; do not copy a real vehicle model, brand mark, protected character, or a living creator's recognizable style. Build the image with these requirements: 1. Subject: show exactly one vehicle in a readable front-side three-quarter view, occupying roughly 45% to 55% of the lower half. Keep the axles, body, cabin, and ground contact physically coherent. Add no driver, passenger, or unrelated prop. 2. Motion system: start from one visible wheel hub or energy module and construct five to eight rings, semicircles, calibrated arcs, and radial lines at varied scales. Let them connect foreground, midground, and background without hiding the silhouette, headline, or important mechanical structure. 3. Information hierarchy: place {two digits} as an oversized cropped numeral behind the subject. Set {headline} exactly in the upper-left safe area, with {small subhead} directly below. Show only these three specified text groups; generate no logo, brand name, fake certification mark, QR code, tiny specification table, or gibberish. 4. Color and light: use the body, accent, and background colors as three clearly separated layers. Apply one directional key light with restrained reflective highlights. Avoid blown mirror glare, uncontrolled neon, and inconsistent shadows. 5. Visual language: combine flat geometric fields, a small amount of technical line work, paper grain, subtle registration offset, and sparse alignment marks. Keep the system original and editorial; do not imitate an existing automotive campaign, racing poster, or brand identity. 6. Quality check: credible vehicle proportions, a stable ring count, correctly spelled numeral and titles, text clear of the subject, crisp line edges, and a composition that remains legible as a card thumbnail after the 4:5 crop. Avoid real trademarks, unauthorized vehicle models, real-person identity, political or military insignia, weapons, illegal modification instructions, dangerous driving, collisions, injury, sexual content, gore, watermarks, random letters, extra vehicles, duplicated wheels, broken structure, floating parts, plastic material, and multi-panel layouts. Return one finished image, not a contact sheet.
