"A photorealistic depiction of the three main characters from the Harry Potter series: Harry Potter, Hermione Granger, and Ron Weasley. Harry is a young boy with messy black hair, round glasses, and a lightning-shaped scar on his forehead. He is wearing wizarding robes, holding a wand, and has a look of determination. Hermione is a young girl with bushy brown hair, bright eyes, and an intelligent expression. She is holding a book and dressed in her Hogwarts school uniform. Ron is a tall, red-haired boy with freckles, dressed in a casual outfit with a Gryffindor scarf. He has a friendly and slightly nervous look. The three of them are standing together, surrounded by a magical atmosphere with Hogwarts castle faintly visible in the background. The image should be highly detailed and photorealistic, capturing their distinctive appearances and the magical world around them."
