Luxury Rooftop City Portrait

A photorealistic luxury rooftop lifestyle portrait of a {argument name="subject" default="young woman"} during blue hour in a modern city. She has fair skin with realistic natural texture, softly defined facial features, and shoulder-length {argument name="hair color" default="blonde"} hair styled in a relaxed, slightly tousled manner, with a few loose strands naturally framing her face. Her expression is calm and confident, with a subtle closed-mouth smile and direct eye contact with the camera. She is standing naturally beside a sleek rooftop railing, using one hand lightly against the railing while the other arm rests comfortably at her side. Her posture is relaxed and elegant, with a slight three-quarter turn toward the camera. The composition should feel like a candid luxury travel photograph rather than a heavily posed studio image. She is wearing a {argument name="clothing" default="deep red, elegant one-piece swimsuit"} with wide shoulder straps and clean, structured tailoring. The fabric should have a realistic matte texture with subtle stitching and natural folds. Keep accessories minimal and sophisticated, small understated earrings and a delicate bracelet, with no visible logos or branding. The setting is a high-end rooftop terrace overlooking a large modern city skyline at dusk. Tall illuminated skyscrapers rise in the background, with countless warm city lights gradually appearing as the sky transitions from soft lavender and pink near the horizon to deeper blue above. Include a glass-and-metal balcony railing, contemporary rooftop architecture, subtle architectural lighting, and a few tasteful outdoor furnishings. The city should remain recognizable as an urban environment without referencing a specific celebrity or person. Use soft twilight ambient light combined with subtle warm architectural lighting on the terrace. The woman's face should be naturally illuminated with gentle, balanced highlights while retaining realistic shadows and skin texture. The distant city lights should produce a beautiful soft bokeh effect.
