Aurora Unicorn: 3D Render Beneath Northern Lights

A hyper-detailed photorealistic 3D render of a majestic unicorn standing on a snow-covered plain at night beneath the northern lights. The unicorn has a gleaming white coat with a subtle pearlescent sheen, a flowing iridescent mane and tail, and a long spiraled horn with a faint inner glow. The aurora borealis overhead displays vivid green and purple curtains, casting volumetric colored light across the scene. Snow crystals drift in the cold air, with distant pine forests and snow-capped mountains in the background. Camera positioned at knee level, slightly to the left, with shallow depth of field to keep the unicorn in sharp focus while the background blurs softly. Materials feature physically based shading, subsurface scattering in the fur, realistic ice-like reflections on the snow, a translucent glowing horn, and fine micro-details on the fur. Lighting is cinematic with rim light along the unicorn silhouette from the aurora, subtle blue ambient illumination, and a gentle glow from the horn and eyes. Render at ultra-high resolution (8K) with global illumination, volumetric lighting, subtle bloom on the aurora, and crisp winter textures. Composition: unicorn slightly left-of-center, head turned toward the aurora, leaving space for the northern lights to arc across the sky.
