祖母と孫のスナップを色褪せない記念ポートレートへ

Transform the uploaded grandmother-and-granddaughter snapshot into a timeless National Grandparents Day heirloom portrait. Preserve both people’s exact identities, ages, expressions, hairstyles, affectionate closeness and natural proportions. Keep a waist-up composition, change their casual clothes to understated coordinated cream and soft blue garments, and move them to a sunlit garden veranda with refined natural light and gentle photographic depth. Retain realistic mature skin texture and the child’s authentic features. Do not de-age the grandmother, change ethnicity, add extra family members, text or painterly facial distortion.
