Anonymized Schoolgirl by Classroom Window

Create a realistic vertical portrait photo of a student_subject standing beside tall classroom windows in warm morning sunlight. She is shown from about mid-thigh up, in a three-quarter back/side pose, looking slightly toward the camera while resting one hand on the white window ledge. Her face is deliberately anonymized by a centered soft-edged square blur/mosaic block in natural skin tones, covering the entire face but leaving the hair and ear visible. She has long straight dark brown to black hair falling past her shoulders with glossy highlights. She wears a school_uniform; include blazer cuff buttons, fitted seams, a small pocket flap, and crisp fabric details. The setting is a Japanese classroom with light wooden floor, rows of wooden desks and metal-framed chairs on the right, a green chalkboard and cork bulletin board with pinned papers in the background, and large bright windows on the left showing a softly blurred outdoor city or schoolyard view. Use shallow depth of field, natural window light, soft shadows, realistic camera perspective, subtle lens blur, high detail, calm candid atmosphere, and a clean photographic style. Canvas should be vertical 3:4, full-color, no text, no watermark, no extra people.
