Dual-exposure narrative poster

Create a high-aesthetic collector poster in a "silhouette universe / dual-exposure narrative" style for an original theme called "Moonlit Dragon Court". Choose the most symbolic outer contour yourself — not a bottle or hourglass, but a more resonant form like a mask, archway, wing, throne, face profile, or luminous gate. Inside and around that contour, let a complete theme world naturally unfold: palaces, bridges, moonlit water, dragon motifs, relics, banners, distant figures, and layered atmospheric depth. The image must feel like a premium novel/anime poster: elegant, mythic, poetic, not cluttered, not collage-like, with strong visual memory and restrained luxurious design.
