Lifestyle Content — Side-by-Side Results
Prompt
"A mid-20s woman with shoulder-length wavy brown hair in a cozy oversized cream sweater and black leggings holds her phone slightly above eye level for a casual selfie video, looking near the camera while stirring an iced latte with the other hand. She’s seated by a window in a small neighborhood café with a half-open laptop and tote bag on the table, candid “work day” vibe with warm natural window light and subtle background blur. Shot feels like an Instagram story frame—unposed, relaxed expression, a few loose strands of hair, everyday ambience."
