"Create an image with a 9:16 aspect ratio, depicting an urban alleyway in an incredibly realistic, photographic manner. This image, to be used as a background, must feature intricate details such as brick walls, windows, pipes, and traces of city life like trash cans and debris, closely mirroring reality. A dim but notable light source enhances the atmosphere, illuminating parts of the scene. Moreover, a UFO appears in the sky, casting a clear beam of light toward the urban alleyway. This beam from the UFO adds a mysterious and mystical ambiance, emphasizing a sense of immersion and realism as if viewers were present in the scene. Emphasize a Japanese boy in the lower left of the frame, making him the focal point as he adopts a welcoming pose, with open arms and a face filled with joy, as if greeting a dog. This portrayal of the boy and his anticipatory stance towards Fluffy adds a dynamic human element, further enriching the narrative depth and emotional impact of the image." --ar 9:16
