Native tall portrait aspect ratio exactly 9:16, target1080x1920. Use case: ads-marketing. Create a photorealistic editorial beauty diptych, an explicitly fictional hairstyle length visualization, NOT real customer results. Same adult woman age 34 in both panels, exact matching face, brown eyes, warm olive complexion, dark chestnut brown hair, same ivory crew neck top, same neutral expression, same three-quarter rear pose with her face visible turned slightly toward camera. Left panel chin-length bob; right panel same woman with hair reaching middle of back. Both lengths equally natural, healthy, same density/part/color; length alone differs. A pair of equally sized adjacent photographic panels on a rich muted cornflower-blue studio background. Top 24% of overall canvas empty blue for later headline. Portraits occupy middle from 28% to 80% canvas, woman visible head-to-waist in each, no cropped hair ends. Bottom 17% empty blue for later explanatory copy. Tiny slim amber 30ml Wonder Hair Serum bottle standing in foreground at lower center, about 18% of image height with its bottom at 94% canvas height. Use input 1 only for exact physical bottle identity and input 2 for label; black tall pipette bulb and ribbed collar, amber glass, cream rectangular label WHOLESALE BOTANICS /100% BATANA OIL/WONDER HAIR SERUM. Bottle must be completely within bottom middle region and not block hair ends. No text anywhere other than bottle label; deterministic headline and visible AI illustration disclosure will be added separately. Studio fashion photography with realistic skin and strands, no artificial glossy perfect hair, no changing age/face/body between panels, no dates, no arrows, no fake reviews or performance claims. Compose natively for requested ratio, not a crop.
