A half-body shot of a cute petite

A half-body shot of a cute petite high school girl with black ponytail, in a school rooftop under a bright midday sun. She has long black hair tied in a high ponytail, fair skin, and is wearing a white short-sleeved sailor uniform with a red neckerchief and dark pleated skirt. Leaning forward toward the viewer, she places both hands on a railing behind her, head tilted, offering a playful mischievous smile and wide twinkling eyes. In the background, the blurred city skyline sits under a clear sky with faint cloud trails. The scene is lit by sharp sunlight casting distinct shadows, rendered in a high quality anime illustration with vibrant colors and crisp lines.
