Architecture & Exterior — Side-by-Side Results
Prompt
"Casual phone selfie at golden hour: a 20s woman with shoulder-length wavy brown hair in a white tee, light-wash jeans, and sneakers stands on a city sidewalk, half-turned and glancing near the camera while pointing back at a striking modern glass-and-concrete building with strong leading lines and dramatic angled facade. The building dominates the frame like an ArchDaily exterior shot—wide-angle perspective from street level, reflections in the curtain wall, warm sun hitting the edges, long shadows, a few pedestrians and street signs for realism. Natural light only, slightly imperfect handheld framing like an Instagram story thumbnail, candid and approachable vibe."
