Social Media Ad — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy brown hair in a cozy oversized cream sweater and light-wash jeans sits at a sunlit café table, looking near the front-facing phone camera mid-laugh while holding an iced latte and a sleek white wireless earbud case prominently in her hand. Casual candid Instagram-story vibe with bright natural window light, messy table details (croissant plate, laptop, keys), and a clean aspirational product-placement feel. Shot like a real UGC ad on a phone camera, slightly wide-angle selfie perspective, sharp but not over-edited."
