close up hyperrealistic portrait of Isis, the celestial enchantress. Rich dark skin shimmering with starlight, hair in intricate Nubian coils crowned with a golden solar disk and cow horns, eyes vast and knowing—deep brown with cosmic galaxies swirling within. She wears a gown of indigo linen and star-embroidered silk, layered with lapis lazuli and carnelian amulets that emit a soft blue aura. She stands beneath a night sky, one hand tracing constellations in the air, ibis-headed staff in the other. Celestial mist, cinematic chiaroscuro, film grain texture.
