A stunning, futuristic scene where the architecture of a grand building seamlessly merges with a Christmas tree, forming a single, harmonious structure. The building is sleek and modern, with glass and steel elements, but its design subtly transforms into the shape of a Christmas tree as it rises upwards. The tree's branches, made of bioluminescent foliage, glow in festive colors, blending naturally with the architectural lines and curves of the building. The entire structure, both tree and building, is adorned with shimmering lights, ornaments, and decorations, creating a striking fusion of urban and natural forms. The scene is set in an expansive urban plaza, where the tree-building stands tall and majestic against the backdrop of a twilight sky, filled with vibrant hues of purple, pink, and orange. Soft snowflakes gently fall around the scene, adding to the magical, holiday atmosphere. The image captures the perfect balance between technology, architecture, and nature, creating a visually captivating and surreal Christmas vision
