Unreal Winter Landscape

Only Nano Banana Pro can make winter look this unreal. Prompt: A cinematic winter landscape featuring a futuristic concrete vault built into a snowy hillside. A bright emerald-green glowing crystal structure is visible inside the upper window of the vault. Snow is falling softly under a moody teal sky. A lone person in a white winter jacket stands on a metal walkway leading to the vault, looking up at the glowing window. Cold atmosphere, dramatic lighting, high-detail photography, ultra-realistic, 4K.
