A photorealistic, cinematic classroom scene featuring a young female teacher standing at a large chalkboard, (slim), ((huge round ass:1.4)), viewed from behind. She is reaching up to erase the blackboard with one hand, creating a natural stretched pose. She is wearing a tight, ((usually white midi dress that hugs her figure)), with long sleeves, paired with white high-heeled shoes. Her blonde hair is neatly styled in a bun. The chalkboard is filled with mathematical equations, formulas, and handwritten notes, adding an academic atmosphere. Warm sunlight streams through a window from the side, casting soft shadows on the wall and chalkboard, creating a dramatic yet natural lighting effect. The setting is a modern classroom with minimalist design. The composition emphasizes depth, symmetry, and realism, with strong attention to fabric texture, natural body proportions, and realistic lighting. The mood is calm, sophisticated, and slightly cinematic, blending elegance with an intellectual environment, ultra-realistic photography, cinematic lighting, golden hour sunlight, shallow depth of field, high resolution, ultra-detailed, fashion-meets-academic aesthetic, vertical composition, professional photography look
