A cinematic, ultra-detailed wide-angle concept art photograph of a colossal, heavily armored military space battlecruiser in high orbit over a decaying planet. The massive spaceship, dominating the right side of the frame, features a complex, intricate industrial design with dark grey hull plating, hundreds of glowing blue, cyan, and red interior lights, complex turrets, hangars, and panel lines. The cruiser has multiple modular sections and powerful, complex engines at the rear. It is positioned diagonally, facing towards the upper left. A bright, blazing white sun is located in the upper-left corner of deep space, casting a powerful, diagonal blue lens flare across the dark void and silhouetting the left-front hull of the ship. Below the ship, the fragmented surface of a rocky, brown-and-orange planet is visible, scattered with countless large and small dark asteroid and planetary debris fragments floating in the vacuum. A thick, turbulent layer of ethereal, glowing teal and cyan gas or a massive nebula plume separates the ship from the planet, creating a dramatic atmosphere. A small, delicate mechanical tether/crane hangs from the underside of the vessel. The overall color palette is a stark contrast of deep blacks, blues, and electric cyan against the warm, earthy tones of the broken planet. The atmosphere is epic, cold, and apocalyptic.
