A professional, hyper-realistic portrait of a teacher standing confidently in a bright white classroom. A clean blackboard is behind her, with soft natural light filling the room. She has straight black hair and a slim, elegant silhouette. She is standing tall and body facing the blackboard, both hand touch the blackboard. She wears a neat blue blouse tucked into a modest black skirt, creating a polished and professional look. The overall atmosphere is academic, clean, modern, and inspiring.
