Replace “surrounded by dozens of translucent jellyfish” with “three distant translucent jellyfish framing the edges,” and change “sharp focus on the face and hair” to “sharp focus on the woman’s full body and face, jellyfish softly blurred in the background.” Keep “dramatic vertical composition” so her silhouette remains the central axis.

Replace “dark sapphire water” with “clear midnight-blue water,” “ethereal and haunting atmosphere” with “serene, luminous atmosphere,” and “gentle phosphorescent accents” with “radiant warm-gold and turquoise bioluminescent light.” Change the dress highlights from “blue and violet tones” to “turquoise and soft gold” to move the palette away from dominant purple and black.

Replace “an elegant woman floating vertically” and the details “pale skin, wet silver-gray hair, and matte deep-purple crystal-scale dress” with a new subject block such as “a porcelain-faced diver in a weathered brass suit, floating vertically with a trailing red silk scarf.” Retain “dozens of translucent jellyfish,” “dark sapphire water,” “dramatic vertical composition,” and “9:16 aspect ratio” to preserve the same series identity while changing the character.
