Replace “sharp focus at macro scale” with “extreme macro focus locked on the visible eye, razor-sharp iris and pupil,” and add “eye centered near the upper third of the frame.” Keep “side-profile close-up” so the eye remains visually dominant without losing the snake’s profile.

Change “vibrant futuristic neon color palette” to “dark bioluminescent noir palette with restrained magenta accents,” and replace “smooth deep-cyan background” with “near-black seamless background.” Revise “dramatic studio lighting with pronounced rim light” to “low-key lighting with a narrow cold rim light and deep facial shadows.”

Keep the fixed structure, including “close-up side-profile portrait,” “sharp focus at macro scale,” “smooth deep-cyan background,” and “dramatic studio lighting with pronounced rim light.” Replace only “iridescent snake” and its color phrase with controlled variants such as “emerald tree python with lime and cobalt scales,” “white cobra with pearl and scarlet scales,” or “black mamba with graphite and electric blue scales.”
