ศึกปิดล้อมป้อมปราการไซไฟสไตล์โกธิก

A wide-angle digital painting of a massive sci-fi siege battle at dusk. In the foreground, heavily armored super-soldiers stand atop a fortified rampart, firing heavy rifles emitting bright orange muzzle flashes. The warriors wear ornate power armor in [yellow, dark grey with white star emblems, blue with red accents, and weathered white]. Behind them, regular soldiers in olive drab uniforms and combat helmets operate heavy machinery and artillery batteries. In the background, a colossal Gothic fortress with towering spires and flying buttresses is silhouetted against a smoky, fire-lit sky. Swarms of gunships and drop-ships fill the air amidst flak explosions and tracer fire. Dramatic cinematic lighting, high-contrast war scene.
