プロンプト

Cinematic natural-history documentary realism: a solitary musk ox standing in a remote subarctic plain, small and slightly off-center in the lower third, with wind-bent grasses, scattered frost, distant low hills, and a broad atmospheric horizon beneath a vast open sky illuminated by sweeping pale-green aurora. Cool twilight, faint residual light along the horizon, deep blue shadows, weathered brown fur, and soft snow-white highlights create a powerful, solitary mood with controlled visual noise. No text, watermark, logo, border, or interface elements.
