Instagram Model — Side-by-Side Results
Prompt
"A 22–28-year-old Instagram influencer with long wavy brunette hair and natural glowy makeup, wearing an oversized beige hoodie and black biker shorts, holds a phone slightly above eye level for a casual selfie while looking near the camera with a relaxed half-smile. She’s standing in a bright kitchen making iced coffee, messy bun clip on the counter, sunlight coming through the window with soft warm color grading and subtle ring-light catchlights for a curated-but-real IG story vibe. Shot on a phone-camera feel, candid framing, slightly imperfect background clutter (dish rack, fruit bowl) to keep it authentic."
