Replace “bright cool-white backlit background” with “soft warm-gray studio background,” change “high-contrast lighting” and “crisp rim light” to “large diffused key light with gentle facial modeling,” and replace “silhouetted man” with “man with softly visible facial features.” Keep “teal-tinted lenses” if you want a cool accent against the warmer setting, or change it to “amber-tinted lenses” for a fully warm palette.

Replace “portrait-closeup” with “extreme close-up focused on the eyes and glasses,” and change “centered composition” to “symmetrical head-and-glasses framing.” Expand “sleek futuristic glasses with teal-tinted lenses and a thin metallic frame” to “oversized futuristic glasses with luminous teal lenses, reflective surfaces, and a clearly visible brushed-metal frame,” while reducing “smooth dark contours of head, neck, and shoulders” to “only the upper face and glasses visible.”

Keep the fixed anchor phrases “photorealistic minimalist studio portrait,” “sleek futuristic glasses,” “centered composition,” and “crisp rim light,” then vary one controlled block per image. Swap “bright cool-white backlit background” for “deep cobalt gradient,” “soft silver haze,” or “matte black studio,” and replace “upward-facing gaze” with “direct eye contact,” “downward gaze,” or “profile-facing gaze” to create distinct compositions while preserving the same subject and lighting signature.
