A bioluminescent cosmic jellyfish floating through infinite deep space, translucent dome cap pulsing with inner galaxy glow, dozens of flowing ethereal tentacles trailing behind with trailing star dust wisps, single large luminous eye with detailed nebula reflections, cel-shaded with bold black outlines, dynamic floating composition with cosmic particle streams and floating stardust, deep cosmic black and bright neon magenta cyan purple palette with magical cosmic glow, serene mystical mood, scattered floating cosmic bubble wisps and distant galaxy spiral silhouettes, cosmic sea creature concept art with soft bokeh of distant star clusters and falling starlight curtains
