AI Prompt for Realistic Subway Street Photo with Birthday Billboard and Influencer Model

"Create a realistic wide-angle documentary photo inside a clean Korean subway station corridor with tiled walls, ceiling panels, polished gray floor, and platform signage in the background. On the left foreground stands a young woman with long dark hair, wearing an oversized blue denim jacket, white graphic T-shirt, black mini skirt, and casual shoes, smiling but with her face anonymized by a soft rectangular blur; she poses with both hands pointing toward a giant illuminated wall billboard. The billboard fills the right two-thirds of the image, framed in black, and shows a pastel idol birthday advertisement with a large portrait of the same young woman also anonymized by a rectangular blur over the face, long dark hair, denim jacket, and white shirt. The billboard design has a dreamy pink-to-turquoise blue gradient background with sparkles, bokeh, floating petals, small wing and heart decorations, and a small crown above a pink ribbon banner. Include Korean fan-ad typography: the ribbon reads “여신 탄신일”, the huge central name reads “윤슬”, smaller Korean congratulatory lines sit beneath it, and the large date reads “1996.02.15”; along the bottom edge include tiny English text like “YOONSEUL DAY • ALWAYS BE WITH YOU • FROM YOUR STARLIGHT”. Make the scene feel like a celebratory K-pop fan subway birthday ad photo, with natural station lighting, slight lens distortion, realistic reflections, sharp billboard text, and no extra people in the foreground. Customizable details: use the featured name {argument name="character name" default="윤슬"}, birthday date {argument name="birthday date" default="1996.02.15"}, ribbon text {argument name="ribbon text" default="여신 탄신일"}, billboard color palette {argument name="billboard color palette" default="pastel pink and turquoise blue"}, and outfit {argument name="outfit" default="oversized blue denim jacket, white graphic T-shirt, and black mini skirt"}."
