A female anthropomorphic arctic fox, ethereal celestial deity style, full body portrait from the knees up. Elegant and slender physique with precise measurements of 90-40-110. Adorned in flowing, multilayered robes of iridescent nebula-silk that shift through hues of deep cosmic blue, ethereal violet, and star-dusted silver, cinched at a narrow waist with a constellation-engraved platinum girdle before flowing over pronounced hips. A magnificent, luxuriant tail of pure white fur, so dense it appears sculpted from fresh snow, is elegantly coiled around her slender legs, its tip dusted with a faint, shimmering stellar glitter. She stands poised on the edge of a floating marble balcony amidst the clouds, overlooking a swirling galaxy and nebulae in a twilight sky. One gracefully articulated hand, with fingers tipped in mother-of-pearl, rests lightly on the cool, polished railing, while the other cradles a faintly pulsating crystalline orb containing a miniature, swirling cosmos. Her posture is one of serene, absolute authority. Her face is a vision of otherworldly beauty, piercing, almond-shaped eyes the color of liquid starlight with pupils shaped like distant galaxies, a delicate black nose, and a knowing, subtle smile playing on her lips. Long, silken hair the color of moonlight falls in waves, interwoven with strands of translucent, glowing astral energy and tiny, twinkling stars that float in an unseen breeze. Wispy, luminous markings resembling celestial charts grace her alabaster fur along her cheeks and brow. An intricate, weightless-looking diadem of woven moonlight and captured stardust floats just above her forehead.
