Romantic 3D CG Yuri Illustration

Generate a 9:16 vertical, high-precision 3D CG double character illustration. The overall style is high-end 2D 3D CG rendering, with a dreamy, romantic, ambiguous, and restrained texture. The subjects are two adult Eastern fantasy female characters, located by a huge bright floor-to-ceiling window. Left character: adult female, {argument name="left hair color" default="silver-white short hair"}, gentle and active eyes. Right character: adult female, {argument name="right hair color" default="bright red long hair"}, high ponytail, calm expression. The two have an intimate relationship: their noses almost touch, and their eyes meet in an ambiguous gaze at close range. Both wear {argument name="dress color" default="white"} fantasy-style modified short formal dresses in a unified style. The background features a backlight effect from the floor-to-ceiling window, with warm golden-pink sunset soft light.
