Ciudades Flotantes Isométricas en Acero Damasco

A 2x2 grid featuring four famous cities ([Paris, Tokyo, New York, London]) in an isometric dreamscape. In each panel, a flat vintage 2D map of the city lies below, with a perfect isometric 3D cubic chunk of the city hovering directly above its corresponding location on the map. The entire 3D architectural block, including skyscrapers, bridges, and exposed geological strata, is meticulously crafted out of glowing [magma damascus steel]. Stylized rivers cascade off the edges of each cube like miniature waterfalls pouring into the void. Soft, fluffy stylized clouds drift around each floating block. Bright, airy, pastel lighting with subtle miniature texture details.
