Create a highly realistic 3D model of a sea turtle with detailed, lifelike textures. The shell should have natural roughness, subtle color variations, and realistic pattern markings. The skin must show fine scales, wrinkles, and natural imperfections. Include detailed eyes with natural reflections. Render the sea turtle in a neutral pose, with accurate anatomy, proportions, and realistic shading. The model should look suitable for close-up inspection, photorealistic, and true to a real ocean sea turtle
