Solid deep-red seamless backdrop and red floor, monochrome red environment. Subject is leaning/sitting in a relaxed pose with one hand slightly raised near the face (fingers softly bent), the other hand resting lower near the waist. Add a strong multi-exposure / motion-echo effect: 2–3 translucent offset duplicates trailing to the right, like a long-exposure movement smear. Keep the main face sharp and dominant, with the echoes softer and semi-transparent. Lux editorial retouching, crisp fabric texture, subtle skin texture, cinematic contrast. Clean image: no text, no logos, no watermark."
