Fashion Photography — Side-by-Side Results
Prompt
"A 24–30-year-old woman with shoulder-length wavy dark hair in a casual oversized beige hoodie, bike shorts, and white sneakers holds her phone slightly above eye level for a front-camera selfie, glancing near the lens with a relaxed half-smile mid-walk. She’s on a real city sidewalk outside a neighborhood café with a paper coffee cup in hand, messy street reflections in the window behind her, golden-hour natural light and mild motion blur like an Instagram story. Keep it unpolished and authentic—subtle skin texture, imperfect framing, and everyday background clutter."
