Brand Campaign — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy dark hair, minimal makeup, wearing a cream oversized hoodie and black bike shorts, holds an iced coffee and glances toward the phone camera mid-laugh while walking past a sunlit neighborhood café patio. Shot like an Instagram Story with a handheld phone at arm’s length, natural window light and soft shadows, but with clean commercial-grade clarity and subtle brand-consistent color grading (warm neutrals, crisp skin tones) as the branded reusable cup is clearly visible in her hand. Authentic everyday vibe—slightly messy hair, candid motion blur in the background, real street details (menu board, bikes, passing pedestrians)."
