Waving Schoolgirl in Sunlit Hallway

Create a high-quality vertical anime-style portrait of a cheerful Japanese high school girl in a sunlit school hallway. She is turned slightly away from the viewer but looking back over her shoulder with a gentle smile, raising one open hand in a friendly wave. She has glossy black hair styled in two loose braided pigtails with soft wispy bangs, large warm brown eyes, delicate round wire-frame glasses, smooth fair skin, and a subtle natural blush. She wears a classic sailor-style school uniform: a white short-sleeve blouse, navy sailor collar with two white stripes, a red necktie, and a dark pleated skirt. The hallway background is softly blurred with windows on the left, cool blue-gray walls, and strong late-afternoon sunlight streaming in, creating bright rim light, dappled highlights on her hair and shirt, and cinematic depth of field. Use polished modern Japanese anime rendering with semi-realistic lighting, detailed hair strands, soft painterly skin, expressive eyes, clean linework, and a warm nostalgic school-life atmosphere. No text, no watermark, no extra characters.
