Replace “relaxed editorial pose with a natural expression” with “upright formal posture with a composed, direct expression,” and change “light blue linen shirt with sleeves slightly rolled and dark charcoal trousers” to “deep navy tailored suit, crisp white dress shirt, and polished black leather shoes.” Keep “seated cross-legged” if you want authority with a less rigid silhouette.

Replace “seated cross-legged in a rugged dark textured chair” with “seated cross-legged in a minimally visible chair, centered and filling most of the frame,” and change “portrait-full-body” to “three-quarter portrait framing.” Retain “shallow depth of field” while adding “background strongly blurred and chair texture subdued” to reduce competing detail.

Keep “photorealistic studio portrait,” “crisp facial detail,” “realistic skin texture,” and the subject’s age and pose unchanged, then swap only the wardrobe and backdrop phrases. For example, replace “warm taupe backdrop” with “cool slate-blue backdrop” and “light blue linen shirt...dark charcoal trousers” with “cream knit polo and olive trousers” for one variation, or use “muted terracotta backdrop” with “soft gray overshirt and black trousers” for another.
