Enchanted Fantasy Landscape with Unicorn and Rainbow

In this magical scene unfolds an enchanting fantasy landscape where the whimsical charm of unicorns meets the grandeur of castles. A majestic unicorn adorned in a rainbow mane and tail frolics joyfully by a meandering stream that reflects its playful figure. Beyond lies a stately castle perched atop rolling hills under a sky painted with a resplendent rainbow arching gracefully across it. Heart-shaped leaves dance from tree branches swaying gently to the rhythm of unseen breezes, while the distant mountains stand as silent sentinels guarding over this realm of wonder.
