지하 거대도시 중앙 타워 옥상

Cinematic dark sci-fi concept art of [Tokyo Geofront central tower rooftop], viewed from a high oblique aerial angle. An immense cylindrical white-gray industrial tower rises from a vast subterranean megacity cavern. The broad circular rooftop platform features concentric rings, panel seams, industrial vents, antennas, modular machinery blocks, safety railings, and weathered modular armor plating. Exactly four massive elevated bridges extend radially from the rooftop in a symmetrical cross layout toward the surrounding cavern walls, each bridge damaged and clad in exposed pipes and structural trusses. In the background and far below, a deep vertical abyss reveals countless tiny warm yellow window lights within dense decayed industrial cliffside districts, scaffolds, and eroded concrete structures beneath a rocky cavern rim. Gritty hard-surface mecha and anime game environment style, photorealistic concept art rendering, desaturated charcoal and off-white color palette, cold top-down ambient lighting with glowing pinprick lights below, heavy atmospheric haze, dramatic scale and deep shadows. No people, no vehicles, no readable text, no logos.
