Purple-haired witch with starry hat

A vertical anime-style illustration of a beautiful witch in profile view, facing right. She has long flowing purple hair and wears an elaborate black witch hat with gold trim, decorated with star patterns, a large purple gemstone at the front, and small purple flowers on the side. The underside of her hat brim reveals a starry night sky pattern. She wears a dark cloak with gold accents and a matching brooch featuring a purple gemstone. Her eyes are purple, and she has delicate earrings shaped like stars. In the background, there's a magical nighttime scene with a crescent moon, scattered stars, and a silhouette of a large cat's face in the clouds. Below, a gothic castle or city with lit windows sits beside a river reflecting the lights. The overall color palette is dominated by deep purples, blacks, and gold accents, creating a mystical atmosphere.
