Colossal Hard-Sci-Fi Spaceship with Sensor Spires & Industrial Detailing

In the style, mood, and visual aesthetic of the reference image: a colossal asymmetrical deep-space flagship with modular docking rings, towering sensor spires, exposed engineering decks, illuminated observation galleries, and intricate industrial detailing, drifting above a blue planetary horizon. Surrounded by uniquely designed escort vessels and distant orbital stations, with moons and luminous nebula clouds in the background. Epic hard-sci-fi realism, immense scale, weathered metal surfaces, dense mechanical detail, cinematic orbital lighting, dramatic perspective, photorealistic spacecraft design. Color palette dominated by steel blue, gunmetal gray, charcoal black, cold silver, pale planetary blue, dusty teal nebula tones, soft white highlights, and muted amber lights. Ultra-detailed concept art, masterpiece.
