Whimsical Island with Floating Castles

A fantastical island scene with floating castles above lush, green landscapes. The castles are designed with intricate details and painted in pastel blues and pinks. The sky is a bright, clear blue with fluffy clouds, and a sparkling waterfall cascades from one of the floating castles into a crystal-clear lagoon below. A group of explorers marvels at the spectacle, adding a sense of wonder.
