Night Rugby Player Portrait

Create a photorealistic sports portrait of a smiling rugby_player standing on a muddy rugby field at night after a match. He is centered in a medium shot from thighs to head, facing the camera with relaxed confidence, wearing a black padded scrum cap, wrist tape, muddy white shorts, and a short-sleeve rugby jersey with broad horizontal jersey_colors stripes and a small shield-style crest on the left chest. His face and arms are lightly muddy, his jersey is heavily stained with wet dirt, and visible breath vapor hangs beside his head in the cold air. The background is a softly blurred stadium pitch with wet grass, puddles reflecting light, faint spectators, tall rugby goalposts on the right, and bright floodlights glowing in the upper left. Use shallow depth of field, realistic rain or mist particles, cinematic documentary sports photography, natural skin texture, high dynamic range, cool night color grading, crisp subject detail, and authentic post-game atmosphere. No text, no watermark, no exaggerated muscles, no extra players in the foreground.
