Portrait anime, cinematic, dark urban, elegant

Create a highly detailed dark fantasy anime-style portrait depicting a mysterious young witch against an ornate celestial gothic background. The subject is a beautiful female sorceress with , facing the viewer in a close three-quarter view, her face deliberately obscured by a centered rectangular mask with a warm brown skin-tone gradient. She wears a huge black pointed witch hat with an extremely wide brim and a tall twisted conical crown, covered with exquisite antique-gold filigree, thorn-like metal vines, tiny stars, crescent moons, hanging chains, and jewel-like decorations. Her outfit is a black lace off-the-shoulder gothic dress with translucent tulle sleeves, floral lace trim, beading, and shimmering gold accents; one bare shoulder and a slender hand near her lips are visible. The hat brim must include 6 prominent hanging celestial ornaments: 3 stars, 1 crescent moon, and 2 small chain charms. The background is a luxurious and fantastical white palace city with towers, spires, arches, and cathedral architecture, above which is a dim starry sky; behind the hat is a huge ornate golden circular mirror or halo, and on the right is a floating spiral staircase made of dark wooden books. Use . The light and shadow should be cinematic, atmospheric, and magical, with flickering highlights on the metallic filigree, accompanied by floating starlight, presenting a luxurious and highly detailed digital painting texture. Composition: vertical portrait, close-up crop, hat occupying the upper half, face mask centered, palace background with depth, extremely intricate textures, creating an elegant mysterious atmosphere. Avoid modern objects, text, logos, watermarks, extra characters, or facial features visible under the mask.
