Golden Hour Chiaroscuro Portrait

Ultra-realistic IMAX-level Netflix-style cinematic dark-warm portrait, 4:5 vertical composition, use the uploaded image as the primary facial reference with maximum face consistency, create a beautiful young adult woman in an intimate three-quarter close portrait with her body slightly turned and her face angled sideways. Her expression feels intense, mysterious and quietly magnetic, with softly lowered brows, sharp side-glancing eyes, relaxed cheeks, softly parted lips and a refined feminine jawline. Her luminous fair porcelain milky-white skin rendered with ultra-smooth clean texture, soft natural pink freshness and perfect even face-to-body skin tone consistency. Her dark hair is styled in a loose elegant updo with a few soft face-framing strands. She wears a sleek black spaghetti-strap dress with a subtle satin-leather look and a delicate layered necklace. Use a deep dark background with rich amber-golden light cutting dramatically across her face, neck, collarbone and shoulders, creating strong shadow contrast, a moody editorial atmosphere, warm highlights, soft skin glow, cinematic depth and premium photorealistic detail, highly detailed 8K quality. Negative Prompt: flat lighting, cool tone, bright background.
