3. Rational Mini-Me Bag Guard Version Generate a creative image in high-end realistic fashion photography style, vertical 4:5 aspect ratio, light gray minimalist background, soft natural studio lighting. The main subject is an adult young woman wearing a simple and elegant beige trench coat, white top, and trousers, carrying an exquisite small white bag on her shoulder, walking forward confidently with a calm yet slightly smug expression. At the bottom of the frame, a miniature version of herself appears, sharing the same appearance, hairstyle, and clothing style. This tiny, cute, 3D-rendered "mini-me" is holding onto the bag with both hands, wearing an exaggerated, serious, and slightly aggrieved expression, like a "rational little steward" reminding her to calm down. The main subject's body remains moving forward, creating a natural, slight tension between the bag strap and the mini-me, with the bag's position and physical force logic clearly depicted. The overall requirement is a realistic photographic texture, high-end fashion advertising feel, strong contrast in scale, and a lighthearted, humorous narrative, like "the rational me reminding the impulsive me." No extra characters, no complex background, no logos, no watermarks.
