Create a hyper-realistic diorama depicting an ancient cosmic whale carrying a floating island city for the 3D chibi-style miniature design of a whimsical celestial leviathan. A colossal yet adorable cosmic whale, adorned with bioluminescent barnacles, gently transports a vibrant, multi-tiered floating island city on its back. The miniature city buzzes with tiny steampunk-inspired buildings and intricate pathways, thriving in harmony with the giant. Details to include: Miniature, glowing airships tethered to city spires. Tiny waterfalls cascading into cosmic ether. Bioluminescent algae trails on whale's skin. Small, curious chibi-style humanoid figures peering over ledges. At the bottom, a subtle, elegant text overlay: 'aisuperhub.io'. Suspended in a swirling nebula of iridescent blues, purples, and deep cosmic blacks, studded with twinkling stars. Ethereal rings of gas and dust encircle, imparting immense grandeur. A glowing energy field below hints at cosmic currents. Ethereal, soft glow from the nebula, backlighting whale and city with a majestic, dreamlike aura. Warm golden light highlights buildings and ancient scales, evoking wonder. Vibrant cosmic blues, nebulous purples, emerald greens, and soft pearlescent whites, accented with golds and coppers from the city. Awe-inspiring tranquility and whimsical exploration.
