Eastern Vintage Mythological Decorative Poster

Generate a vertical 3:4 Eastern vintage mythological decorative poster with the theme "[Theme Name]". The main subject is a [mythological figure / mythical beast / deity], positioned on the right side of the image, drawn in an extremely fine Eastern line-art style, with intricate clothing or body details, including [cloud patterns / flame patterns / dragon patterns / ritual objects / headdresses / ancient decorative motifs]. The overall subject uses off-white, pale gold, and gray-white tones, without realistic thick painting. Behind the subject, place a huge warm golden circular sun wheel or moon wheel to create a divine backlight effect. The background uses large areas of cinnabar red, deep black, ink green, or dark gold color blocks, overlaid with ancient architectural silhouettes, mountain outlines, wave patterns, talisman patterns, and decorative borders. In the foreground, add several low-saturation indigo auspicious clouds or misty color blocks that partially obscure the subject and background, enhancing the flat compositional feel. The overall style is Eastern mythology, vintage advertising poster, decorative art, silkscreen print, old paper texture, grain noise, and color registration offset. High-end composition, clear color blocks, intricate details but with clear layering. On the left side, add a vertical large title "[Chinese Title]", and beside it add small English decorative text "[English Subtitle]". No 3D, no modern neon, no chibi, no game UI, no cheap guochao, no watermark, no real logo.
