Create a hyper-realistic digital painting depicting a bustling futuristic city for the hyper-realistic isometric 3D render of a miniature metropolis encapsulated within the translucent bell of a colossal, bioluminescent jellyfish, adrift in a cosmic ocean. The city pulses with iridescent light; spiraling towers and sky-bridges cling to the jellyfish's inner membrane. Sleek vehicles navigate glowing arterial paths, inhabitants visible through semi-transparent walls of this impossible, living habitat. Details to include: intricate glowing data streams like rivers; a central holographic park with alien flora; observation decks into the gelatinous void; transparent dome neighborhoods; and energy conduits powering the city. The immense jellyfish drifts through a star-dusted cosmic ocean, its tendrils like nebulae. Distant galaxies glimmer, while closer celestial bodies illuminate its outer surface, creating dynamic light patterns filtering into the inner city. Soft internal bioluminescence from the jellyfish casts an ethereal, dreamy glow, complemented by vibrant, multicolored artificial city lights. This creates focused brilliance and contemplative shadows, evoking awe, wonder, and serene optimism. Palette dominated by deep cosmic blues, purples, iridescent greens, glowing teals, and vibrant fuchsia. Touches of silver/white for structures, soft ethereal pinks/oranges from internal organs. An atmosphere of impossible tranquility and advanced utopian existence pervades this otherworldly habitat.
