Strong rule: style --- 3D Pixar ---. Portrait of a 40-year-old male swim coach, athletic muscular build, stern square jaw with furrowed brows, short salt-and-pepper hair, piercing eyes, wearing navy polo shirt and khaki shorts, holding stopwatch. Disapproving expression. Bright pool lighting casting shadows on face, blurred indoor pool background, realistic style with sharp details, dramatic chiaroscuro, 9:16 vertical format.
