Diorama en Papier Découpé de Bibliothèque Cosmique

A highly detailed 3D layered papercraft diorama set inside a floating cosmic library, blending fantasy and steampunk aesthetics. The central composition features [a thoughtful young explorer with long silver-streaked hair tied in a loose braid], wearing [an elegant deep navy coat with brass accents] and a glowing pocket watch suspended on a chain, gently placing a glowing book onto a levitating pedestal. Surrounding her are miniature handcrafted versions of herself engaged in different tasks: deciphering ancient runes on floating stone tablets, piloting a tiny airship crafted of parchment and gears, sketching constellations on an unrolled star map, and repairing a mechanical owl built from layered paper and copper textures. The setting is an expansive, dreamlike library of stacked levitating books, spiral staircases dissolving into starlight, and glowing knowledge orbs floating mid-air, against a deep indigo space background with subtle nebula clouds and abstract golden constellation maps. Premium handcrafted papercraft aesthetic with visible layered edges, intricate shadow depth, soft cinematic rim lighting, and a [rich color palette of midnight blue, antique gold, glowing cyan, and parchment beige].
