Frost Sovereign Cathedral Anime

anime style, highly detailed, cinematic composition, 1girl, 
long silver white hair flowing upward, cold piercing golden eyes, 
expressionless stoic face, wearing a black high-collar military 
coat with gold trim and epaulettes, fitted trousers, heeled boots, 
standing tall with arms crossed, head slightly tilted down, 
gazing forward with quiet intensity, massive glacial ice shards 
erupting from the floor around her, frost spreading across the 
ground beneath her feet, frozen ice crystals floating in the air, 
grand cathedral interior, shattered rose window, moonlight 
piercing through broken stained glass, frozen candles suspended 
mid-drip, deep blue and white color palette, mist curling along 
the floor, dramatic cold atmosphere, ethereal glow, 
caption text "Frost Sovereign!" in sharp gothic font 
at bottom center, masterpiece, best quality, ultra-detailed
