Champ de Bataille d'Invasion Sci-Fi Vue Aérienne

An ultra-wide cinematic science-fiction war panorama from a [high aerial reconnaissance drone FPV viewpoint], tilted down over a massive apocalyptic battlefield. Setting: [devastated industrial city and military base in a mountain valley], with distant mountain peaks beneath [stormy late afternoon under dark clouds]. On the left sky, 1 colossal alien mothership made of layered black metallic armor plates, glowing [violet purple] lights, and angular blade-like spires, surrounded by dozens of smaller alien gunships and drones. On the ground: 2 towering bipedal alien war mechs advancing, hundreds of miniature infantry figures, and rows of human tanks, armored vehicles, artillery batteries, trenches, and defensive fortresses across the right and lower foreground. Action & Lighting: Diagonal streaks of [violet purple] plasma beams rain from the alien fleet, countered by bright orange-white tracer rounds and artillery flashes from human defenses. Dense volumetric black smoke columns, burning wreckage, bright sparks, glowing embers, and multiple explosions across the center and lower-left ground. Style: [photorealistic cinematic sci-fi concept art], IMAX disaster scale, cold gray atmospheric color grading contrasted with vivid energy fire, extreme depth of field, sharp photorealistic details, no text, no borders, no watermark.
