A girl with long black hair in a dramatic three-tier waterfall bun secured with a full set of gold and ruby diankou and trembling buyao step-shake ornaments, large prismatic crystal wings refracting rainbow light in all directions, floating above a mirror-still salt flat, wearing a white Tang dynasty ruqun with geometric black ink-line patterns across the skirt panels and a flowing cape shifting through the full color spectrum like oil on water, gold court necklace with three jade loops, holding a perfect glass sphere containing a miniature supernova of swirling colors, a single enormous black monolith standing on the infinite white salt flat behind her, stark white sky creating an overexposed ethereal atmosphere, dominant palette of pure white, absolute black, and explosive rainbow refractions, prismatic light beams shooting outward from her wings, minimalist centered composition with vast negative space emphasizing her figure against the monolith --ar 9:16 --sref ••••• --niji 7
