Strong rule: style --- 3D Pixar ---. A professional man in his mid-30s with a serious and calm expression, featuring an oval face, fair skin, and deep-set brown eyes. He has short, neatly trimmed dark hair and a full, well-groomed dark beard that is slightly longer at the chin. He has an athletic build with broad shoulders, standing with his arms crossed confidently. He is wearing a crisp white medical lab coat over a dark shirt with a visible blue collar. His gaze is direct and steady, conveying a sense of authority and competence.
