A medium shot from a slightly low angle depicts a graceful young prince riding atop a majestic unicorn within a royal palace garden. The prince has iridescent opal-colored hair with bangs framing his forehead, and he wears a joyful, beaming expression. He is dressed in ornate, royal attire featuring gold embroidery and silk fabrics, with his hands gently gripping the unicorn's iridescent reins. The unicorn is a magnificent creature with a shimmering white coat and a flowing, rainbow-colored mane and tail that glisten with a pearlescent sheen. They are positioned centrally in a lush, fantastical royal garden filled with exotic glowing flora, manicured hedges, and towering white marble arches of the palace in the distant background. The atmosphere is ethereal and dreamy, illuminated by a soft, celestial glow with floating light particles and a pastel color palette. Soft-focus depth of field creates a magical, hazy quality to the surrounding greenery and architecture.
