Character anime illustration, night scene, warm, elegant

Create a highly detailed anime fantasy illustration depicting elegantly sitting on a dark wooden library ladder stool in a giant ancient magical library. She is a young elegant witch with very long flowing hair and violet eyes, reading an open dark magic book with golden astrological symbols. She wears a luxurious deep midnight-blue and black full astral mage outfit with ornate gold embroidery: 7 major clothing pieces are visible in the image, including 1 oversized pointed witch hat with a wide brim, 1 star-and-sun crown ornament inlaid with a large blue gem, 1 slim dark fitted dress with white ruffled lace trim, 1 short layered skirt lined with light-colored ruffles, 1 long asymmetrical cloak covered with constellations and zodiac patterns, 2 black over-the-knee stockings with gold garter details, and 2 glossy black high-heeled ankle boots decorated with dangling Venus chains and blue gems. Add abundant delicate gold chains, star pendants, crescent moons, constellations, pearls, and blue gems on the hat, cloak, neckline, sleeves, waist, thighs, and boots. Her pose is calm and slightly shy, one knee raised, the other leg sloping downward, both hands holding the book, face turned toward the viewer, with a soft and mysterious expression. The background is a towering Victorian-style mystical library, filled with floor-to-ceiling bookshelves, warm sunlight, carved wood, brass railings, and many astronomical instruments. Include 5 prominent magical library props around her: 1 open astrology book in the foreground, 1 brass armillary sphere on the right, 1 glowing blue orb on a stand on the left, 1 hanging lantern above, and 1 leafy green plant beside the bookshelf on the right. Use rich deep blue, gold, bronze, and warm amber tones, with sparkling dust, intricate linework, luxurious fabric textures, deep depth of field, and cinematic lighting. Vertical composition, ultra-detailed, refined Japanese anime style, elegant fantasy fashion illustration, no modern objects, no extra characters, no watermark, no visible signature.
