Instagram Model — Side-by-Side Results
Prompt
"A 20s Instagram-model-style woman with long glossy dark-brown hair in a loose claw-clip, natural glam makeup, wearing an oversized oatmeal hoodie and black biker shorts, holds her phone slightly above eye level for a casual front-camera selfie while glancing near the lens with a half-smile. She’s standing in a bright kitchen making iced coffee (mason jar, espresso machine, open fridge in the background), one hand mid-stir, candid “morning routine” vibe with soft window light and clean, curated home aesthetic. Subtle warm color grading, realistic skin texture, minimal clutter, looks like an authentic IG story screenshot."
