Photorealistic close-up image of malfoidvx, an adult Slytherin witch inside the Hogwarts potions classroom. Wearing a fitted white shirt with rolled sleeves, loosened emerald-and-silver tie, and charcoal sweater vest, she leans over an ancient wooden workbench, delicately holding a glass vial of glowing emerald potion between her fingers. Her platinum-blonde hair falls over one shoulder as she looks directly into the camera with a calculating, confident expression and faint knowing smile. Shelves of mysterious ingredients, bubbling cauldrons, ancient stone walls, and curling green magical vapor in the background. Dramatic emerald illumination across her face, cinematic shadows, shallow depth of field.
