Incredible Anime Yin Yang Twin Girls Showcase

Create a square anime style illustration of two young women forming a yin yang taijitu composition while floating or lying in a soft dreamlike space. The image contains exactly 2 characters: one upper left girl with {argument name="upper character hair color" default="long flowing chestnut brown hair"}, blue eyes, pale skin, and a translucent white sleeveless slip dress; and one lower right girl with {argument name="lower character hair color" default="long flowing deep navy blue hair"}, blue eyes, pale skin, and a translucent white loose dress. They are curled toward each other in mirrored fetal poses, their bodies and hair creating a circular swirl, like the two halves of a yin yang symbol. The upper girl faces downward with one hand near her face and her legs folded; the lower girl is upside down relative to the viewer, gazing upward with one arm bent over her head and legs tucked. Their bare feet and delicate limbs are visible, with graceful anatomy and gentle expressions. Use a pastel watercolor and colored pencil anime rendering style with soft linework, luminous skin highlights, sheer fabric folds, flowing hair strands, and a tranquil emotional tone. The background is an abstract circular wash of {argument name="background colors" default="misty blue, lavender, peach, and soft coral"}, painted with swirling brush textures that reinforce the taijitu shape. No text, no border, no watermark, no extra characters; keep the composition centered and fill the square canvas with the circular intertwined pose.
