Create a 3D digital artwork of a building visualized in an X-ray aesthetic. The structure should be portrayed with its internal framework resembling metallic bones, forming the fundamental supports and beams as if they were the skeletal structure of a living organism. At the core of the building, place a large, glowing object representing the heart, which should emit a soft, pulsating light, suggesting that it’s the vital energy source for the entire structure. Emphasize contrast in your rendering, with bright highlights on the metallic bones against a darker, semi-transparent exterior of the building. Set a cool-toned, minimalistic background to enhance the visual impact of the X-ray effect and the metallic anatomy of the building
