1920年代黑幫肖像

A highly technical JSON prompt for generating a hyper-cinematic 1920s noir gangster portrait of a young man. It uses an image-to-image mode with medium identity strength to influence the face from an uploaded reference, focusing on low-key lighting, high contrast, and specific wardrobe (fedora, trench coat) to create a mysterious, intense atmosphere.
