Architecture & Exterior — Side-by-Side Results
Prompt
"Casual phone-camera selfie of a 20s woman with shoulder-length dark hair in a beige hoodie and black leggings, holding an iced coffee and looking slightly past the lens with a relaxed half-smile while standing on a city sidewalk in front of a striking modern glass-and-concrete building; dramatic low-angle perspective with strong leading lines from the building facade and street curb. Golden hour natural light with warm reflections in the windows, subtle motion blur from passing pedestrians, authentic Instagram story vibe (handheld framing, imperfect crop, everyday candid moment)."
