Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright, centered — Marina Sergeevna, a fictional middle-aged Russian schoolteacher, roughly late 40s. Warm oval face with soft laugh lines, tired but kind hazel eyes behind slim rectangular glasses, fair skin, faint blush. Chestnut-brown hair with a few grey strands, gathered into a neat low bun with a couple of loose flyaway wisps by day's end. Sturdy, motherly build of average height. She wears a modest teal knee-length button blouse-dress with a slim belt, a soft grey cardigan over the shoulders, a thin scarf, and comfortable low black flat shoes. Around her neck hangs a lanyard; she clutches a stack of exercise notebooks and a red pen. Expression: strained patience edging toward weary resolve. Setting: a bright classroom with a chalkboard, wooden desks and tall windows behind her.
