Midjourney
Retro-futuristic floating city, adorned in atompunk clothing with intricate metallic details, glowing atomic motifs, and retro-futuristic designs, set against a backdrop of atomic reactors, vintage sci-fi machinery, and geometric cityscapes. Rendered in the style of mid-20th-century propaganda art with a modern twist, featuring a vibrant yet controlled color palette of chrome silver, radioactive green, deep crimson, and electric blue. The composition emphasizes bold lines, glowing highlights, and a sense of dynamic energy, evoking a nostalgic yet forward-thinking aesthetic. --ar 3:4
