Keep “close bust framing,” but replace “a small cluster of floating dim-white light cubes held in midair” with “no floating objects, unobstructed face,” and add “sharp focus on the eyes and facial plating, centered head-and-shoulders portrait.” Change “warm amber-gold eyes” to “bright luminous amber eyes with crisp catchlights” for a stronger focal point.

Replace “gentle volumetric haze” with “dense shadow-filled smoke,” and change “neon lighting shifted to teal and violet” to “deep crimson and indigo neon with hard side-lighting.” Replace “floating dim-white light cubes” with “flickering red warning lights,” and add “severe underlighting, heavy facial shadows, threatening atmosphere.”

Keep “photorealistic futuristic cybernetic human bust,” “fragmented ceramic-and-metal plating with subtle gold veins,” and “close bust framing” unchanged, then swap only the setting and palette: use “emerging from black liquid in a flooded laboratory” with “cold blue and silver lighting,” or “rising from cracked volcanic glass” with “orange-red lighting and drifting ash.” Retain “warm amber-gold eyes” in every version as the recurring visual signature.
