"Create an image with an aspect ratio of 9:16, depicting an urban alleyway in a photo-realistic manner, intended to be used as a background. It should closely resemble reality, featuring brick walls, windows, pipes, and urban debris like trash cans that showcase traces of city life. A dim yet significant light source illuminates parts of the scene. A UFO appears in the sky, casting a distinct beam of light onto the urban alleyway, adding a mysterious and mystical ambiance. Emphasizing immersion and realism, the scene makes viewers feel as though they could step right into it. Additionally, include a Japanese boy in the scene, who is adopting a welcoming pose towards Fluffy, indicating his readiness to greet the creature. This inclusion of the boy and his interaction with Fluffy introduces a dynamic human element, further enriching the narrative depth and emotional impact of the image." --ar 9:16
