A Grand Christmas Tree in Chicago Union Station

Photorealistic, ultra-detailed 8k image of a magnificent Christmas tree in the grand interior of Chicago Union Station. The towering tree rises above a marble concourse with ornate stone arches and a vaulted glass ceiling. Warm golden fairy lights twinkle through the dense green branches, adorned with red and gold ornaments, ribbons, pinecones, and a bright star topper. A diverse crowd of travelers in cozy winter coats gathers around, their reflections shimmering on the polished floors. Daylight streams in through large arched windows, blending with the tree’s glow to create a festive, cinematic atmosphere. In the background, gold-trim balconies, clock faces, and glimpses of trains add depth and scale. Textures include cool gray stone and marble, glossy tiles, velvet jackets, glass and metal railings. Color palette combines warm golds and greens with cool architectural tones. Style: photorealistic, cinematic lighting, wide-angle perspective (16-24mm), slight tilt for grandeur, high dynamic range, subtle film grain.
