Colossal Mecha Robot Over European City

Cinematic ultra-realistic shot of a colossal 300-meter-tall white-and-gray humanoid mecha robot towering over a dense modern European city beside a wide river, late afternoon golden-hour light with soft haze and volumetric god rays. The giant robot has intricate mechanical details: heavy armored plating, exposed pistons, hydraulic lines, riveted joints, weathered paint with subtle rust and battle damage, massive articulated fingers and feet crushing the ground. Low-angle dramatic perspective from street level looking straight up, showing the robot's enormous legs and torso dominating the frame while the city (skyscrapers, historic buildings, bridges, boats on the river) appears tiny far below. Dust and smoke rising from its footsteps, river water rippling from the impact.
