Epic silhouette worldbuilding poster

Design a collector's-edition epic poster for an original fantasy theme called "The Celestial Archive". The outer silhouette is a graceful side profile of a lone archivist, and inside that silhouette a complete world naturally grows: observatories, floating stairways, bridges, ancient libraries, moons, towers, relics, and distant pilgrims. Make it feel like a narrative silhouette composition rather than a collage. Style: cinematic poster fused with dreamy watercolor illustration, quiet and majestic, sacred and nostalgic, with paper grain, soft mist, brush-edge texture, elegant negative space, and a discreet signature "WHY" integrated naturally as part of the layout.
