PRIMARY IDENTITY ANCHOR: use the uploaded reference photo of the target adult man. Replace the man in ALL panels with the reference identity while preserving the original pose and expression intensity. Keep suit-and-tie styling and clean studio background. Maintain consistent identity across all 16 panels."
