Loyal Dog in a Dim Concrete Bunker

A highly detailed digital painting of a loyal dog sitting inside a dim concrete bunker. Rough gray walls, rusted metal bunk, and survival crates line the chamber. A bank of flickering fluorescent tubes casts cold light while a warm amber glow from a small lamp caresses the dog's fur. Neon-blue reflections from nearby screens illuminate the scene with a cyberpunk vibe. Dust motes drift in a beam of light through a small porthole, and old computer monitors display maps and schematics. The atmosphere is hopeful yet somber, with cinematic lighting, painterly textures, and a sense of quiet guardianship in a post-apocalyptic shelter.
