Professional Headshot — Side-by-Side Results
Prompt
"A candid phone-camera headshot of a 25–32-year-old influencer with shoulder-length dark brown hair in a simple low ponytail, wearing a smart-casual knit crewneck sweater under a light blazer, looking near the camera with a relaxed half-smile. Shot against a clean muted light-grey wall corner in their apartment (minimal, uncluttered) as if they’re filming an Instagram Story intro, shoulders slightly angled and one hand adjusting their blazer lapel. Soft natural window light from the side, realistic skin texture, subtle shadows, unretouched everyday vibe."
