Photorealistic full-body image of malfoidvx, an elegant adult Slytherin witch walking confidently through the snow-covered stone courtyard of Hogwarts Castle. She wears a tailored black winter coat over her Slytherin uniform, a long emerald-and-silver striped scarf, black skirt, dark tights, and polished knee-high leather boots. Her long platinum-blonde hair moves gently in the cold breeze. She walks toward the camera with an upright aristocratic posture and a cool, self-assured expression, one hand adjusting her scarf. Snow-covered gothic archways, ancient castle towers, and softly falling snow surround her. Muted winter daylight, cinematic atmosphere, realistic full-body proportions, fashion editorial composition.
