Anonymous Schoolgirl by Window

Create a realistic cinematic photograph of a subject standing indoors in a quiet school hallway beside a large window, shown from the waist up in side profile as she gazes outside. She wears a dark navy sailor-style school uniform with a pleated skirt, white double-striped sailor collar, and a muted red necktie; her long straight black hair falls past her shoulders. Her face is intentionally obscured by a soft square mosaic blur centered over the facial area, preserving anonymity. The hallway behind her is dim and slightly out of focus, with a door and frosted rectangular window panel visible in the background. The right side of the image is dominated by tall white-framed windows and a pale windowsill, with a rainy or overcast outdoor view of distant hills, buildings, greenery, and a faint reflection of the girl in the glass. Use natural soft daylight, muted cool colors, shallow depth of field, subtle film grain, contemplative mood, photorealistic 35mm documentary style, vertical square composition, no text, no watermark.
