Diorama 3D in carta della Biblioteca Cosmica

A highly detailed 3D layered papercraft diorama set inside a floating cosmic library, blending fantasy and steampunk aesthetics. The composition centers on a {argument name="character" default="thoughtful young explorer with long silver-streaked hair tied in a loose braid"}, wearing an {argument name="outfit" default="elegant deep navy coat with brass accents"} and a glowing pocket watch suspended on a chain. She is gently placing a glowing book onto a levitating pedestal, as if unlocking a hidden story of the universe.Surrounding her are miniature handcrafted versions of herself in different roles: one deciphering ancient runes on floating stone tablets, another navigating a tiny airship made of parchment and gears, one sketching constellations on a rolled-out star map, and another repairing a mechanical owl made of layered paper and copper textures.The environment is a vast, dreamlike library made of stacked floating books, spiral staircases that dissolve into starlight, and glowing orbs of knowledge hovering in mid-air. The background fades into deep indigo space filled with subtle nebula clouds and golden constellations forming abstract maps.The entire artwork has a premium handcrafted papercraft aesthetic with visible layered paper edges, soft cinematic rim lighting, intricate shadow depth, and a {argument name="color palette" default="rich color palette of midnight blue, antique gold, glowing cyan, and parchment beige"}. The mood feels mystical, intellectual, and epic — like a secret archive of the universe.
