A detailed Victorian lithograph of a fantastical steam-powered city built atop a massive mechanical turtle. Tiny airships buzz around like fireflies, while the city itself is a labyrinth of towering spires, rotating gears, and billowing smokestacks. On the turtle’s back, miniature figures are seen tending to gardens, adjusting machinery, and observing the stars through telescopes. The turtle's massive legs churn slowly through a misty sea. The color palette features sepia tones with hints of brass and muted greens. --ar 16:9 --zoom 1.5 --style steampunk --v 5
