Anime Yin-Yang Twin Girls

Create a square anime-style illustration depicting two young women floating or lying in a soft dreamy space, forming a yin-yang taiji symbol. There are exactly 2 characters in the image: upper-left girl, , blue eyes, fair skin, wearing a semi-transparent white sleeveless slip dress; lower-right girl, , blue eyes, fair skin, wearing a semi-transparent white loose dress. They curl around each other like mirrored fetal poses, their bodies and hair forming a circular swirl like the two halves of a taiji diagram. The upper girl faces downward, one hand near her face, legs folded; the lower girl is upside down relative to the viewer, gazing upward, one arm bent above her head, legs curled. Their bare feet and slender limbs are clearly visible, poses elegant, faces gentle. Use pastel watercolor and colored pencil anime rendering style, soft lines, glossy skin highlights, translucent fabric folds, flowing hair strands, and a serene mood. The background is abstract circular watercolor washes, , with swirling brush textures reinforcing the taiji shape. No text, no border, no watermark, no extra characters; centered composition, filling the square canvas with a circular intertwined pose.
