Colossal futuristic cities rising above a toxic desert world

Massive scale science fiction artwork depicting colossal pillars of steel and white carbon fiber rising from a toxic desert planet. Each flattened pillar supports a vast futuristic city, interconnected by trams and strong tubes. Centered within each city is an immense spaceport, with spaceships actively arriving and departing. Cinematic lighting emphasizes the grand scale and futuristic aesthetic, rendered in a highly detailed digital matte painting style reminiscent of Sparth and Syd Mead, with a dramatic, desaturated color palette conveying a sense of alien grandeur.
