A photorealistic Indian woman in a classroom

A photorealistic image of an adult Indian woman in her early 20s seated at a wooden desk in a bright university classroom. She has medium-brown skin, dark hair pulled back into a neat low bun, and a calm, focused expression. She wears a professional navy blazer over a white blouse with a light pink scarf, appropriate student attire. In front of her lie an open notebook and a textbook; she is writing with a pencil. The classroom features rows of desks, a chalkboard with faint equations, a world map on the wall, and a small potted plant by the window. Warm morning sunlight pours through large windows to her left, casting soft shadows and giving the scene a shallow depth of field. The image should be highly realistic with detailed skin texture, natural hair, fabric folds, and believable lighting.
