A dreamy watercolor depiction of an expansive castle nestled among soft, fluffy clouds, bathed in delicate hues of pastel pinks, blues, and lavenders. The castle's spires pierce the misty sky, adorned with ethereal banners that flutter gracefully in an unseen breeze. Gentle wisps of cloud wrap around the castle's base, their iridescence reflecting the subtle shifts in daylight, creating a serene atmosphere of whimsy and magic. Delicate details hint at enchanting gardens hidden within the castle walls, where the pastel tones are mirrored by vibrant blossoms, blending seamlessly into the celestial surroundings.
