Replace “charcoal-gray suit” with “warm mid-gray or muted navy suit,” change “burgundy tie” to “soft rust or muted teal tie,” and replace “soft warm beige studio backdrop” with “sunlit cream studio backdrop.” Keep “smiling,” “friendly, professional expression,” and “gentle rim light” so the expression and subject separation remain intact.

Replace “medium-tight character portrait framing” with “tight head-and-shoulders close-up,” and change “clean centered composition” to “face-centered composition with the beard and eyes as the primary focal point.” Reduce the wardrobe competition by replacing “light blue dress shirt and a burgundy tie” with “simple white shirt with no tie,” while retaining “natural glossy skin highlights” for facial definition.

Keep the fixed identity and structure phrases, including “smiling man with a refined beard,” “facing the camera,” “centered,” “soft warm beige studio backdrop,” and “elegant modern studio lighting with gentle rim light.” Create controlled variants by changing only one field at a time, such as replacing “charcoal-gray suit” with “navy suit,” “burgundy tie” with “forest-green tie,” or “dark brown hair” with “black hair,” while preserving the same framing and expression.
