The peak is partially draped in wisps of low-hanging clouds and mist, creating a dreamy atmosphere. Dense evergreen forest forms a dark silhouette in the foreground, while the mid-ground slopes are detailed with snow trails and natural rock striations. The sky is filled with a mix of deep indigo, mauve, and golden-orange clouds, with light breaking through from the left side, illuminating the scene with a soft, cinematic glow. Photorealistic, high detail, 8k resolution, golden hour lighting, ultra-realistic rendering, Unreal Engine style landscape scene, hyper-detailed textures, moody and atmospheric."
