Ice Cave Turtle in 3D Render

Ultra realistic 3D render of a sea turtle in an ice cave. The turtle stands on a frozen glassy floor beside a shallow turquoise pool. The cave walls are carved from translucent blue ice with intricate fractures, jagged stalactites and frost. Soft volumetric light beams filter through the ice, creating caustics on the shell and water. The turtle shell shows realistic patterning, slight wear, and a subtle frosty glaze. Skin features detailed scales and wrinkles with a glossy wet look. Colors are cool blues and cyans with a warm amber highlight from a distant crack. Reflections and refractions on ice, subsurface scattering for shell and skin. Slight depth of field with background ice gently blurred. The render should be high resolution photorealistic CGI with physically based lighting and materials, a low to mid camera angle in a three quarter view from the left.
