Create a realistic 3D animation featuring a group of 17-year

Create a realistic 3D animation featuring a group of 17-year-old teenagers standing together. They are all wearing school uniforms that include long-sleeved shirts and long skirts. Each character has a normal body type and is displaying a friendly, enthusiastic expression, reflecting a sense of camaraderie and positive energy. The style should be realistic, with detailed attention to the school uniforms, their posture, and facial expressions.
