Bioluminescent shadow bloom unfolding in a cosmic void

Design an abstract cinematic composition where darkness itself behaves as a flowering organism. From a void like core, layers of shadow unfold outward in petal formations smooth, fluid, and disturbingly graceful. The edges emit faint violet luminescence, as if the absence of light has begun to bioluminesce. Dust motes drift in slow orbit, pulled by gravitational eddies within the bloom’s center. The movement is silent but suggestive of breath, each expansion and contraction rippling through surrounding space. Focus on volumetric layering, gradient shadow behavior, and subtle phosphorescence at petal fringes. Maintain 8K photorealistic fidelity, Unreal Engine 5 level lighting diffusion, color grading between deep indigo, amethyst, and spectral grey. No figures, bodies, or silhouettes pure luminous void aesthetic.
