Prompt
"A 25–32-year-old influencer with shoulder-length dark brown hair in a neat middle part, wearing a smart-casual beige blazer over a plain white tee, holds their phone at arm’s length for a quick selfie headshot, looking near the camera with a relaxed, confident half-smile. Shot against a clean light grey wall in a quiet corner of a coworking café, with soft window daylight and subtle fill for a polished-but-real LinkedIn-meets-Instagram-stories vibe. Natural skin texture, minimal makeup, slightly imperfect framing like a real UGC post."
