Prompt: A masterfully crafted environmental sculpture of a shark created from carefully arranged smooth river rocks and pebbles rests on a natural rocky beach. The sculpture, which occupies the center of the frame, demonstrates exceptional attention to detail in its anatomical accuracy and three-dimensional form. The grey and white stones are meticulously positioned to create texture and shadow, complete with a realistic eye and defined fins. The sculpture is surrounded by a natural beach environment featuring scattered brown seaweed clusters and a variety of smooth stones and pebbles, with the water's edge visible in the background. The scene is captured in natural daylight from a high angle in a medium wide shot, creating a harmonious composition that showcases both the artistic creation and its natural setting.
