Create a hyper-realistic photorealistic scene depicting a bustling steampunk city inside a colossal, translucent dandelion seed, adrift in a cosmic nebula, for a 3D chibi-style miniature of a whimsical time-traveling squirrel mechanic. The intricate city, powered by gears and brass conduits, sprawls across the dandelion's fibers. Tiny airships navigate its structures, as the goggle-wearing squirrel mechanic inspects a chronometer at the city's heart. Details to include: Golden internal city lights, miniature hot air balloons, sparkling stardust, tiny steam vents, and the squirrel's brass tools. The dandelion drifts within a cosmic nebula, a swirling tapestry of iridescent purples and blues. Distant galaxies emphasize its delicate world against infinite space. Magical interplay: warm, golden glows from the city contrast with ethereal luminescence of the nebula's cool blues, creating an enchanting, awe-inspiring atmosphere. Palette: Rich brass, polished copper, warm browns for the city; translucent white dandelion; vibrant iridescent purples, blues, emerald greens for the nebula. The mood is whimsical, adventurous, and wondrous. Hyper-realistic photorealism with intricate, dreamlike fantasy, infused with charming sci-fi illustration. add credits 'aisuperhub.io'
