Photoreal Alien in a Glacial Ice Cave

A photorealistic alien in an ice cave: a slender, humanoid creature with slightly translucent iridescent blue skin that glows with subtle bioluminescent patterns along the spine and limbs. It has large almond-shaped eyes, a smooth elongated head, and no visible hair. The alien stands on a mirror-smooth ice floor beside jagged blue ice formations and delicate icicles hanging from the ceiling. Soft, cold blue light filters through fractured ice, casting volumetric rays and shimmering reflections on the ice walls. Frost particles drift in the air and the alien's breath forms a pale mist. Ultra-detailed textures, realistic skin translucency and subsurface scattering, crisp ice crystals, high dynamic range, cinematic composition with a low-angle view, 35mm lens, shallow depth of field, high detail.
