Epic Futuristic Mecha in Dark Skies

A dramatic cinematic sequence in a dark, dystopian cyberpunk city under stormy overcast skies with thick fog and towering skyscrapers. A massive, heavily armored futuristic aircraft carrier / flying battleship hovers above the metropolis. On its long deck stands a giant white-and-grey mecha robot in dynamic pose, holding weapons.

The camera starts with a high-angle tracking shot from behind as the mecha walks forward along the deck, its footsteps heavy. Bright red warning lights flash rhythmically on the deck. The mecha then turns and strides powerfully toward a colossal multi-barrel naval turret cannon mounted on the ship. The camera smoothly follows and tilts up, focusing on the enormous gun as it elevates, aims skyward, and fires with a massive, intense orange muzzle flash and huge plume of dark smoke billowing into the clouds. Debris and sparks fly. Epic scale, highly detailed mechanical textures, weathered metal, volumetric fog, cinematic lighting, photorealistic yet stylized like high-end sci-fi animation (Ghost in the Shell / Gundam / Starship Troopers aesthetic), dramatic camera movement, 8K detail, moody color grading with cool blues and greys contrasted by glowing reds and fiery orange.
