Photorealistic portrait of a young white woman in a classroom

Photorealistic image of a young white woman in a classroom. She appears to be in her early 20s, with shoulder-length blonde hair, wearing a light gray cardigan over a white blouse, seated at a wooden desk with an open notebook and a pencil in hand. Soft natural light from a window on the left bathes her face and hair. The background shows a chalkboard with simple diagrams, a globe on a shelf, and other students seated at desks out of focus. The camera is at eye level, with a shallow depth of field that keeps her in sharp focus while the background gently blurs. Realistic skin texture, fabric details, and subtle makeup. The mood is calm and studious, as if taking notes during a lecture.
