Photorealistic image of malfoidvx, an adult Slytherin witch standing between towering bookshelves in the restricted section of the Hogwarts library. Wearing a fitted charcoal knit sweater with emerald trim, a short black pleated skirt, and dark tights, with her Slytherin robe draped over one arm. She holds an ancient leather-bound spellbook against her waist while turning her head over her shoulder to look directly at the camera, her expression intelligent, mysterious, and slightly mischievous. Endless shelves of magical books, carved wooden ladders, floating candles, and rich gothic architecture. Warm golden candlelight illuminates her platinum-blonde hair, cinematic three-quarter composition, elegant dark-academia atmosphere.
