A dreamy watercolor scene depicting an expansive castle perched atop fluffy clouds, painted in soothing pastel hues. The castle's towers spiral gracefully into the sky, their tips adorned with delicate gold accents that shimmer subtly in the soft light. Below, gentle swirls of pink, lavender, and baby blue clouds cradle the castle, creating an ethereal floating effect. Wisps of mist curl around the turrets, enhancing the otherworldly atmosphere. The scene is bathed in a serene glow from a sun setting on the horizon, casting a warm, peachy luminescence across the sky, blending seamlessly into the tranquil backdrop.
