Futuristic Mountain Vault in Snow

A cinematic winter landscape featuring a futuristic [concrete vault] embedded into a snowy hillside. Through an upper window of the vault, a bright [emerald-green glowing crystal structure] radiates vivid light. A lone person in a [white winter jacket] stands on a metal walkway leading to the entrance, looking up toward the illuminated window. Softly falling snow under a moody [teal sky], cold atmospheric haze, dramatic high-contrast lighting, realistic textures.
