Prompt
"A mid-20s woman with shoulder-length wavy dark hair in a cozy oversized sweater and leggings holds two smoothie bottles labeled “Nano Banana Pro” and “Seedream 4.5,” looking near the phone camera with a casual half-smile while standing in her bright kitchen by the counter. Candid UGC ad moment: one bottle open in her hand like she’s about to taste-test, the other placed clearly in frame beside a cutting board with bananas and a blender, clean natural window light and slight handheld selfie perspective. Bright, relatable “morning routine” vibe with polished product placement, like a TikTok comparison story."
