Strong rule: style --- 3D Pixar ---. Portrait of Professor Dadali, mid-50s man with lean scholarly build, sharp intelligent hazel eyes behind sleek black-rimmed glasses, short neatly combed salt-and-pepper hair, precise trimmed mustache and goatee framing a thoughtful mouth. Angular face with high forehead and defined jawline, exuding confident wisdom and approachable energy. Wearing pristine white lab coat over slim-fit button-up shirt in pale blue, subtle pocket protector with pens. Dramatic side lighting accentuates cheekbones and creates subtle shadows, cool blue lab backdrop with blurred beakers and charts. Hyper-realistic cinematic style, intricate details, sharp focus, 9:16 vertical composition for mobile video.
