Megaconstrucció steampunk sobre un penya-segat

Epic cinematic aerial shot of a colossal futuristic megastructure rising from a sheer mountain cliff, blending ultra-modern white-and-gold architecture with intricate steampunk mecha base. The lower cliff faces are entirely covered in highly detailed brass, bronze, copper and dark metal mechanical plating, massive gears, pistons, riveted armor, thick steam pipes, and countless glowing circular porthole windows of various sizes emitting warm golden light. Soft white steam and vapor gently rises from the mechanical sections.

Transparent glass-and-metal cylindrical tube roads wind dramatically around and through the structure, with sleek white cars driving inside the enclosed tubes. A bright red Japanese torii gate stands on a circular platform near the center. Towering white and gold skyscrapers with elegant curved spires and golden accents rise into the sky, connected by the tubular highways.

Background: dramatic misty mountains, green valleys far below, bright blue sky with soft white clouds. Photorealistic, ultra-detailed, cinematic lighting, epic scale, 9:16 vertical composition.
