Replace “high-contrast monochrome” and “cooler gunmetal and brushed steel” with “deep bronze, tarnished copper, and warm ivory tones,” and replace “dramatic, enigmatic” with “ornate, inviting, and nostalgic.” Change “crisp reflective highlights” to “soft amber illumination with gentle diffuse reflections” to reduce the severe contrast.

Replace “concentric clock faces” and “centrally framed tunnel perspective pulling inward” with “one oversized clock face in the foreground, centered and occupying most of the frame, with smaller gears receding behind it.” Add “sharpest focus on the central dial and Arabic numerals, background components progressively blurred” so the primary clock clearly outranks the surrounding machinery.

Keep “photorealistic CGI,” “high-contrast monochrome,” “intricate metallic detail,” and “centered tunnel perspective,” then vary only the structural subject phrase, such as “interlocking astrolabes,” “spiraling mechanical lungs,” or “concentric planetary orreries.” Preserve “Arabic numeral dial markings” for clock-themed variations, or replace it with a consistent identifying detail such as “etched geometric calibration marks” across every non-clock design.
