Summer girl with soda splash at poolside AI Image Prompt

A candid summer photo shot from a slightly high angle of a teenage Japanese schoolgirl sitting on wide gray concrete steps beside a bright blue swimming pool. She wears a classic navy-and-white Japanese sailor school uniform with short sleeves, a navy pleated skirt, white knee-high socks, and dark loafers. Her hair is long straight dark brown, falling over her shoulders and chest. She is holding an oversized soft cube-shaped drink container wrapped in a vivid red Coca-Cola print with repeated white logos and bottle silhouettes. The container has a round plastic opening at the top, and exactly 8 long transparent straws are inserted into the opening, extending upward toward her mouth area. Brown soda is splashing upward around the straws and onto her chest and hair, creating a messy, comedic accident effect. Strong midday sunlight, crisp shadows on the steps, realistic skin and fabric texture, documentary-style fashion photo realism, vertical composition, full seated body visible, poolside leisure setting, awkward surreal commercial-photo mood.
