Golden Hour Balcony Portrait
Create a photorealistic lifestyle portrait of a young woman standing on an apartment balcony in a quiet Japanese residential neighborhood at golden hour. She has platinum blonde (hair color) hair styled in two high space buns with loose shoulder-length strands, wearing a muted sage green thin-strap camisole, light high-waisted denim jeans, and a delicate small pendant necklace. Her face is fully covered by a plain centered rectangular privacy block in a warm tan color, with no facial features visible. She is leaning casually against a balcony railing with one arm behind her, upper body framed from about mid-thigh upward. The background shows potted plants on a tiled balcony, an apartment wall and sliding door on the left, railings, rooftops of nearby houses, mid-rise apartment buildings, trees, and a softly hazy evening sky. Use warm low sunlight from the side/back, natural lens blur in the distant cityscape, realistic skin and fabric textures, candid 35mm film-photo feeling, shallow depth of field, square composition, no text, no watermark, no extra people.
