Replace “calm confident expression” with “warm relaxed smile and approachable expression,” and change “soft diffused studio lighting” to “warm golden studio lighting with gentle cheek highlights.” Keep “plain neutral beige-gray background” or replace it with “soft warm taupe background” for a visibly warmer setting.

Replace “tight head-and-shoulders three-quarter view framing” with “tight close-up from the shoulders upward, face centered and filling most of the frame,” and change “shallow depth of field” to “very shallow depth of field with the eyes in crisp focus.” Add “direct eye contact with the camera” if you want the expression to read more forcefully.

Keep the fixed style phrases “photorealistic,” “realistic skin texture,” “soft diffused studio lighting,” and “professional casting headshot look,” then swap “young Black man” for a specific new subject such as “middle-aged South Asian woman” and replace “plain neutral beige-gray background” with options like “muted slate-blue studio background” or “clean warm ivory studio background.” Preserve “tight head-and-shoulders three-quarter view framing” so the images retain the same series composition.
