Her long black hair flows down her back as she dons the iconic Hogwarts uniform: a black robe with a house crest on her chest and a scarf in her house colors. She holds a wand in her hand, poised as if casting a spell. The background is filled with Harry Potter symbols: the towering Hogwarts castle in the distance, floating candles from the Great Hall, a broomstick leaning against a wall, and the Golden Snitch darting through the air, creating a magical and immersive scene straight from the Wizarding World.
