Unicorn Concept Art on a Beach at Dawn

An epic concept art illustration of a majestic unicorn standing at the edge of a sunlit beach at dawn. The unicorn has a pearly white coat, a spiraling luminous horn, and a flowing mane and tail that shimmer with iridescent pastels. The scene emphasizes strong silhouettes and design-readability, with painterly textures and cinematic lighting. The beach features smooth wet sand reflecting the sky, gentle turquoise waves, scattered seashells and driftwood, and distant cliffs and palm silhouettes. The sky is a gradient of peach, lavender, and pale blue, with soft wispy clouds and warm rim light along the horizon. Subtle magical particles hover around the unicorn, and its horn glows softly. Use a mix of bold concept-art lines and painterly shading, with shallow depth of field to keep the unicorn as the focal point. Aspect ratio 16:9 or 3:2, high resolution.
