A medium shot, eye-level anime illustration of a middle-aged male swimming coach standing by the side of an indoor competition pool. The coach is a man in his late 40s with a weathered but fit physique, short cropped salt-and-pepper hair, and a stern yet encouraging expression, with subtle wrinkles around his focused eyes. He is dressed in professional athletic attire, wearing a navy blue polo shirt with a small team logo on the chest, black athletic shorts, and a silver whistle hanging from a black lanyard around his neck. He stands with his arms crossed firmly over his chest, his large hands gripping his biceps, holding a waterproof stopwatch in his left hand. The background features the shimmering turquoise water of the swimming pool, white lane markers, and blurred spectators in the stands under bright, overhead industrial lighting. The visual style is characterized by clean line art, vibrant saturated colors, and realistic water reflections, conveying a disciplined and professional sporting atmosphere.
