霧の中を進む巨大な亀に乗ったスチームパンクの街

A whimsical steampunk town built on the back of a colossal, ancient tortoise as it slowly ambles through a misty, verdant valley. Intricate clockwork mechanisms and brass pipes adorn the buildings, powered by natural steam vents. The art style is reminiscent of detailed watercolor concept art, with soft, diffused light creating a dreamlike atmosphere.
