A premium beauty portrait of an adult woman against a seamless deep red studio background, with dark hair swept cleanly away from the face, refined understated makeup, visible natural skin texture and a calm direct gaze. Vertical shoulders-up close-up with symmetrical placement and an 85mm portrait-lens look. Use a precise butterfly key light above camera, a soft shadow below the nose and restrained rim light around the hair. Crimson, black and warm neutral skin tones, realistic pores and facial proportions, elegant minimal retouching, no jewelry logos, no text, no watermark.
