Digital illustration of a blonde, blue-eyed girl with long, wavy hair adorned with small flowers. She wears a black Hogwarts-style school robe with a yellow trim, a white shirt, a brown vest, a gray skirt, and a striped tie. She sits on a stone ledge in front of a dark, arched brick window. Her right hand rests on the ledge, and her left hand holds a black witch's hat with a yellow "H" emblem. Her expression is slightly surprised or curious. The background is dark with subtle green light from the window. The style is whimsical and cartoon-like, with a focus on soft, warm colors and gentle shading.
