Prompt
"Late-20s woman with shoulder-length wavy dark hair in a relaxed oatmeal hoodie and black leggings, holding a sleek aluminum reusable water bottle while glancing near the front camera mid-sip like she just started filming a TikTok. Standing at a bright corner coffee shop window with laptops and pastries in the background, candid half-smile, one hand on her tote bag strap, natural morning sunlight from the side with subtle commercial-grade fill and clean brand-consistent color grading. Shot as a phone-camera vertical 9:16 Instagram story frame, sharp but authentic, minimal retouching, everyday lifestyle energy."
