Cyberpunk concept art style, synthetic revolution, a black sleek armored robot emerging from a dense sandstorm, imposing silhouette with a pulsating blue eye, clutching a formidable sword, sleek plating catching glints of light, ravaged futuristic cityscape, looming mechanical figure in a turbulent setting, whirling sand vortex and crumbling skyscrapers in the background, ominous robotic titan in the foreground, muted brass and tarnished gold atmospheric lighting, antique gold and patina color palette.
