Replace “smiling” and “friendly approachable expression” with “reserved, thoughtful expression,” and change “warm afternoon sunlight with a gentle golden tint” to “cool overcast daylight with soft blue-gray shadows.” Keep “natural skin tones” to prevent the cooler lighting from making the face look unnaturally pale.

Replace “close-up” with “tight extreme close-up from forehead to chin,” and add “round tortoiseshell eyeglasses sharply in focus, crisp reflections on the lenses.” Retain “shallow depth of field” and “softly blurred outdoor background with bokeh” so the background recedes while the eyewear and facial details stay dominant.

Keep the fixed visual structure, including “eye-level close-up,” “warm afternoon sunlight with a gentle golden tint,” “shallow depth of field,” “natural skin tones,” and “softly blurred outdoor background with bokeh.” Replace only “smiling man with round tortoiseshell eyeglasses and a solid navy polo shirt” with a controlled subject slot such as “smiling woman with silver hoop earrings and a cream linen blouse,” then repeat the same framing and lighting for each variation.
