Coconut Shell Surfing Scene

Create a photorealistic cinematic action image of a young adult man surfing on a giant hollow coconut shell instead of a normal surfboard. The surfer is {argument name="surfer description" default="a handsome young man in his early 20s with short dark wavy hair, athletic build, light-to-medium skin tone"}, wearing {argument name="outfit" default="a fitted black short-sleeve rash guard and black swim shorts"}. He is crouched in a balanced surfing stance with one bare foot forward and one foot back inside the open white interior of the coconut, arms extended for balance, focused expression looking slightly ahead. The coconut shell is oversized, cut open lengthwise like a boat-board, with rough brown fibrous husk edges and glossy white coconut flesh visible inside, riding a turquoise ocean wave. Capture dramatic water splashes, foamy spray, and a curling wave in the foreground with sharp frozen motion. Background: {argument name="beach setting" default="a sunny tropical beach lined with palm trees, colorful umbrellas, lounge chairs, and warm sand"}, slightly blurred with shallow depth of field. Sky is bright blue with scattered fluffy white clouds. Use golden-hour sunlight, vibrant tropical colors, realistic skin texture, wet fabric highlights, dynamic low-angle perspective from water level, 35mm lens feel, high detail, natural shadows, no text, no watermark, no extra limbs, no distorted anatomy.
