Frosty winter scene, icy mist, frost-covered trees, snowflakes gently falling, a majestic frozen lake in the background, a lone figure of a girl with frosty blue hair, pale skin, and icy blue eyes, wearing a warm white coat with fur trim, snow boots, and mittens, holding an icy staff, standing heroically with mist swirling around her legs, cinematic composition, low-angle shot, atmospheric lighting, frosty mist effect.
