Please combine multiple photos of the same person into a photorealistic group photo, retaining the original background of the provided images. Create three avatars, each wearing the same attire but with different poses and expressions (e.g., sitting and smiling, standing and waving and relaxing, or jumping and laughing). The characters should interact naturally, with unified lighting and shadows, creating a realistic and natural image, as if they were a single, multi-person group photo in the original setting.

请将同一个人的多张照片组合成一张逼真的集体照，保留所提供图像的原始背景。创建三个化身，每个化身都穿着相同的服装，但姿势和表情不同（例如，坐着微笑，站着挥手放松，或跳跃大笑）。角色应该自然地互动，有统一的灯光和阴影，创造出逼真自然的图像，就像他们在原始环境中是一张单人、多人的合影一样。
