Please generate images based on the description of each page, ensuring that all images reflect the story's narrative and maintain the consistency of the characters, with all characters matching the given definitions of the four characters. Page 1: Lina (character 1) is happily walking down a bright city street. She's wearing a green outfit, looking cheerful, with her hand raised slightly as if waving to the world. The background features a warm orange sky, with simple modern buildings on both sides of the street, and light-colored brick paving. The entire city exudes energy and vibrancy. The model should reflect Lina's lively personality, with the bright tones of the street complementing the city's energetic atmosphere. Page 2: Lina meets Ajay (character 2), a boy with blue hair and a floral shirt, at the corner of the street. They stand in a candy-colored park, surrounded by dense trees and benches, with colorful flowers dotting the grass. Sunlight filters through the leaves, casting light on them as Ajay shares some recent fun stories, and Lina listens with a bright smile. The model should depict their friendly interaction, with the warm sunlight and natural background enhancing the harmony of the scene. Page 3: As they walk further, they meet Kyle (character 3), a cool boy wearing gray sportswear and sunglasses, performing a high-energy skateboarding trick in the skate park. Kyle is airborne, his skateboard spinning beneath him. The background is a modern skate park, with a dark backdrop highlighting his impressive moves. The model should capture Kyle's dynamic action in the air, emphasizing his personality and the movement of the skateboard. Page 4: Lina, Ajay, and Kyle arrive at the beach, where they meet Xiaohai (character 4), a lively boy holding a surfboard, getting ready to surf. He's wearing a T-shirt with eye patterns, with the backdrop of a vast ocean. The blue sky and white waves meet at the horizon, with the water gently lapping at the shore. The model should convey the freshness of the beach and Xiaohai's excitement, showcasing his anticipation for surfing. Page 5: The four friends play together on the beach under the setting sun, holding hands and forming a circle as laughter fills the air. The background is the golden sunlight reflecting off the sea, with waves gently hitting the shore. The entire scene radiates warmth and the bond of friendship. The model should use the warm glow of the sunset and the friends' smiles to convey the joy and beauty of their time together.
