Speed-Light Double-Exposure Smartphone Portrait

Google Nano Banana Pro Prompt: Generate an image of a man in the uploaded image in which the entire scene is layered with heavy, horizontal motion-blur streaks in shades of teal, yellow, and white, creating a "speed-light" effect. These colorful blurs must appear both behind the man and superimposed over his body and face, behaving like reflections on a glass mirror. A medium shot of a man standing perfectly still in the center of a frame, looking down at a red smartphone held with both hands. He is wearing a white t-shirt under a translucent, light gray windbreaker jacket and a dark wristwatch. The background is a chaotic, vibrant blur of horizontal light trails in colors of neon blue, orange, yellow, and white, suggesting a high-speed train or city traffic. Crucially, these colorful motion-blurred light streaks pass both behind and directly over the man's body, appearing semi-transparent as they overlap his torso and arms, creating a double-exposure effect. The man's face and hair are in sharp focus, showing a calm expression, contrasting with the high-speed motion of the environment. Cinematic lighting, hyper-realistic, 8k resolution.
