Create an image of a young woman in a classroom setting. She has long, straight black hair that cascades down her shoulders, and she is wearing a crisp white button-up shirt with long sleeves. The blouse has a relaxed fit, with the collar slightly open, giving a casual yet polished look. She is standing in front of a classroom chalkboard, which is a deep green color, partially filled with chalk writing. In the background, there are wooden desks arranged neatly, and a clock on the wall indicates the time. The lighting is bright and natural, streaming through a window on one side, casting soft shadows. The young woman is looking directly at the viewer with a calm expression, one hand gently running through her hair. The overall color palette is soft and muted, emphasizing the serene and studious atmosphere of the classroom. The composition focuses on her face and upper body, highlighting her features and the textures of her clothing.
