A glamorous young woman crosses a rain-soaked city intersection barefoot after an all-night party, wearing a silver sequin dress under an oversized black blazer, both heels hanging loosely from one hand. Wet hair, slightly smeared makeup, natural tired expression, captured mid-step rather than posing.\n\nLow 35mm street-level camera, strong asymmetry: she occupies the right third. A plain yellow taxi with NO logos or text sweeps across the left background in soft motion blur. Its wake lifts wet silver confetti into one curved airborne trail behind her, visually tracing her path. Zebra-crossing lines and reflections lead toward her.\n\nCold dawn blue mixes with fading amber streetlights. Smaller condensed white type upper-left: “AFTER HOURS” with generous margin. Small line below: “05:42 AM / STILL GOING”.\n\nRaw, tactile, expensive, candid fashion photography; realistic skin, wet asphalt, sequins, motion and reflections.","aspect_ratio":"1:1","nsfw_checker":true}}'
