A breathtaking etching-style illustration of a fantastical floating city, built upon the backs of gargantuan sea turtles. The city features a blend of Gothic and Baroque architecture, with soaring spires, bridges, and aqueducts traversing the air. Tiny dirigibles and hot-air balloons hover around the turtles, ferrying goods and people. The ocean below is stormy, contrasting with the serene, otherworldly ambiance of the city above. The turtles are rendered with fine texture, their shells etched with ancient symbols, and the architectural details are intricately highlighted. The muted palette features slate blues, faded golds, and stormy greys, evoking a sense of epic grandeur. --ar 16:9 --zoom 1.5 --style expressive --v 5
