Professional Headshot — Side-by-Side Results
Prompt
"A casual, social-media-style professional headshot of a 20s–30s influencer with shoulder-length dark hair in a neat low bun, wearing a smart-casual blazer over a plain white tee, holding their phone slightly above eye level and looking near the camera with a relaxed, confident half-smile. Shot in a real café corner with a clean muted light-grey wall behind them (minimal background distractions), soft natural window light on their face, slight handheld selfie framing like an Instagram story. Subtle everyday details (coffee cup on the table edge, simple stud earrings), realistic skin texture, approachable LinkedIn-meets-UGC vibe."
