Generate a portrait image with strong masculine charisma and high-end visual impact, with aspect ratio {画幅比例}.
This is not an ordinary ID photo, not a cheap glamour shot, not an influencer selfie, and not an exaggerated “domineering CEO” style photo; it should be a male-charisma image that combines high-end commercial portraiture, cinematic character poster qualities, personal brand visual identity, and social-platform shareability.
If the user uploaded a selfie: use the user's uploaded selfie as the primary reference and preserve the subject’s real identity recognizability, including face shape and contours, facial feature proportions, eyebrow-and-eye temperament, basic hairstyle, apparent age, skin tone tendency, and facial characteristics. While keeping the person recognizable, perform a high-end visual translation of the subject: optimize facial lighting and shadow structure; enhance brow bone, nasal bridge, jawline, and facial contours; increase the stability and narrative quality of the gaze; make the hairstyle cleaner and sharper; make skin texture more natural and fresh; make the overall demeanor more mature, more confident, and more authoritative.
If the user did not upload a selfie: by default generate an adult Chinese male with well-proportioned natural features, a poised and appropriate temperament, a clean mature look, a proportionate build, relaxed shoulders and neck, a neat hairstyle, a calm confident expression, and an overall appearance that aligns with the high-end masculine attractiveness of Chinese mainstream aesthetics.
