Strong rule: style --- 3D Pixar ---. Portrait of a 45-year-old male coach, sturdy muscular build from years of athletic coaching, weathered face with strong cheekbones, steely gray eyes showing quiet approval, short salt-and-pepper hair, wearing team polo shirt and whistle necklace, arms crossed with subtle nod of respect. Rugged expression with faint smile lines. Harsh fluorescent lighting casting shadows on face. Background of indoor poolside with lane ropes and timers. Photorealistic sports documentary style, gritty textures and natural skin details.
