Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright, figure centered in an early-morning empty classroom with rows of wooden desks, a chalkboard and tall windows behind her. Marina Sergeevna is a Russian schoolteacher in her late thirties, medium height with a slim, poised build and neat posture. Fair skin, soft oval face, warm hazel eyes, subtle natural makeup, calm composed expression with a faint tired smile. Dark-brown hair pulled into a tidy low bun, perfectly smoothed at the start of the day. She wears a fitted navy-blue blazer over a cream blouse, a knee-length grey pencil skirt, sheer tights, and low black closed-toe heels. She holds a warm coffee mug in one hand, a stack of exercise notebooks on the desk beside her. No text, no watermark.
