"Create a group of diverse cartoon characters, standing side by side and looking straight ahead. Each character should have a unique appearance and personality. One character is a tall, cheerful person with bright blue hair and a big smile. Another is a short, grumpy figure with a round face and glasses. There’s also an athletic character with a confident stance, wearing a colorful tracksuit, and a mysterious, cloaked figure with glowing eyes. The background is simple and brightly lit to focus attention on the characters' expressions and details. Their body language should reflect their personalities, with each one expressing a different emotion."
