Replace “dramatic directional lighting from one side to carve strong shadows” and “high contrast” with “large diffused frontal light, gentle fill light, soft shadows, and low-contrast monochrome.” Keep “pure black background” if you want the subject isolated, or change it to “deep charcoal studio background” for a less stark result.

Change “chest-up framing” to “tight face close-up with the sunglasses occupying the central foreground,” and replace “soft city light reflections in the lenses” with “bright, sharply defined geometric city-light reflections filling both lenses.” Add “slightly lowered camera angle” to give the glasses more visual dominance.

Keep the fixed structure “black-and-white dark editorial studio fashion photo,” “pure black background,” “dramatic directional side lighting,” “high contrast,” and “sharp focus,” then replace the subject description beginning “young man wearing round silver-tone sunglasses” with a controlled variant such as “young woman wearing angular black sunglasses,” “older man with a neatly trimmed beard,” or “androgynous model with cropped platinum hair.” Preserve “chest-up framing” and the same lighting phrase so the series retains its portrait-closeup composition.
