A sealed glass cube containing two beautifully separated worlds. Upper world: warm golden-lit snowy ancient Japanese temples, glowing lanterns, soft falling snow, dense wooden architecture, warm magical winter night, rich detail. Lower world: shimmering icy crystal city glowing in deep blue, crystalline pillars rising like frozen roots, bioluminescent light, ethereal frost mist, a thin luminous membrane divides the two layers. The glass cube edges refract light like a gemstone, subtle rainbow dispersion, tiny floating snow particles suspended inside the cube, placed on a reflective wooden table, background softly blurred mountain village bokeh, dreamy magical atmosphere, hyperreal texture, ultra-detailed lighting, beautiful color harmony (warm gold above, cold blue below), premium art object aesthetic, highly collectible.
