เจ้าหญิงสายรุ้งเดินบนทะเลสาบเวทมนตร์

A vertical fantasy anime illustration of a beautiful rainbow princess walking barefoot across the surface of a sparkling lake, centered full-body shot from head to toe. She has long flowing [chestnut brown] hair whipping dramatically in the wind, large expressive anime eyes, soft rosy makeup, and a jeweled golden crown adorned with rainbow gemstones. She wears an ornate magical princess bodice and short flowing skirt crafted from translucent silk, flower petals, and crystal embroidery, featuring vivid rainbow gradients across the bust and waist, accompanied by a flowing pink chiffon train, delicate gold jewelry, dangling earrings, a jeweled choker, arm ornaments, and ankle jewelry. Her feet create bright ripples and splashes on the water with mirrored reflections beneath her. The setting is a dreamy fairytale valley lake bordered by green hills, distant white village houses, church spires, glowing magical flowers, and drifting pink petals. Overhead, a complete rainbow arcs across a vivid blue sky with fluffy white clouds, sunlit mist, glittering particles, subtle lens flare, and shimmering rain glints. Low-angle perspective, cinematic lighting, vibrant pastel rainbow palette, polished digital anime aesthetic.
