Replace “sleek humanoid robot standing centered on a circular stage” with “towering humanoid robot dominating the circular stage, viewed from a low angle,” and change “cinematic wide framing” to “low-angle wide shot with the robot filling the upper center of the frame.” Keep “sharp focus on the robot” and reduce “soft falloff toward the audience” to “audience heavily blurred and visually subdued.”

Replace “dramatic violet spotlights plus warm amber accents” with “cold cyan and pale blue spotlights with minimal warm light,” and change “faint misty atmospheric haze” to “dense low fog obscuring the stage edges.” Replace “seated in dark silhouette” with “silent audience reduced to indistinct shadow forms” to make the auditorium feel less ceremonial and more threatening.

Keep the fixed anchor phrases “photorealistic cinematic sci-fi,” “sleek humanoid robot,” “circular stage,” “glossy reflective stage floor,” and “semi-transparent holographic interface panels.” For each variation, change only the setting and lighting language, such as replacing “futuristic auditorium” with “orbital command center,” “subterranean research theater,” or “desert communications arena,” while swapping “violet spotlights plus warm amber accents” for a new two-color scheme.
