Instagram Model — Side-by-Side Results
Prompt
"A 23–28-year-old Instagram-model influencer with long dark wavy hair and glossy natural makeup wears an oversized cream sweater and light-wash jeans, holding her phone slightly above eye level for a casual selfie while looking near the camera with a soft half-smile. She’s seated by a café window with an oat-milk latte and laptop on the table, golden-hour sunlight spilling across her face, subtle ring-light catchlights, and a curated, trendy-but-everyday vibe like an Instagram story screenshot. Soft pastel color grading, candid posture (one elbow on the table, other hand tucking hair behind ear), real café background lightly blurred."
