Art style: Vintage Cel Animation.
Full-length view, the entire figure visible from head to feet, standing upright, figure centered in a warm sunlit classroom lined with wooden desks, a green chalkboard and tall old cabinets behind her. Maria Ivanovna is a wise middle-aged schoolteacher in her early fifties, warm fair skin with soft laugh lines, gentle hazel eyes behind round gold-rimmed glasses, and greying chestnut hair pinned into a neat low bun with a few loose strands. Kind, knowing smile with a hint of secrets. Softly rounded, motherly build of average height. She wears a modest high-collared dusty-rose blouse under a fitted charcoal cardigan, a long pleated navy skirt to mid-calf, a small pearl brooch, and comfortable low-heeled brown leather shoes. One hand holds an open worn hardcover book against her chest, the other rests warmly at her side.
