Architecture & Exterior — Side-by-Side Results
Prompt
"Handheld phone photo (vertical 9:16) of a woman in her mid‑20s with wavy dark-brown hair, wearing an oversized beige trench coat, white tee, and sneakers, standing on a city sidewalk and casually glancing near the camera while holding an iced coffee. Behind her is a striking modern glass-and-concrete building exterior shot from a dramatic low angle with strong leading lines and reflections, golden hour sunlight hitting the façade and a soft warm sky. Candid influencer vibe like an Instagram story—slightly imperfect framing, natural street lighting, a bit of motion blur from walking."
