Line-Drawn Deity Halo Poster in Retro Silkscreen

Generate a vertical 3:4 Eastern retro mythological decorative poster, themed «【Theme Name】». The main subject is a 【mythological figure / divine beast / deity】, placed on the right side, drawn in an extremely fine and dense Eastern line-drawing style, with intricate garments or body details including 【cloud / flame / dragon patterns / ritual implements / crown / ancient decorative motifs】. The subject overall uses cream-white, light gold, and gray-white tones, without realistic thick painting. Behind the subject, place a giant warm-golden circular sun or moon halo, creating a divine backlight effect. The background uses large blocks of cinnabar red, deep black, ink green, or dark gold, overlaid with silhouettes of ancient architecture, mountain contours, wave patterns, talisman motifs, and decorative borders. In the foreground, add several blocks of low-saturation indigo auspicious clouds or mist, partially obscuring the subject and background to enhance the flat compositional feel. The overall style is Eastern mythology, retro advertising poster, art deco, silkscreen printmaking, old paper texture, grainy noise, and color-printing offset. Sophisticated composition, clear color blocks, rich details but with distinct layers. On the left, add a large vertical title 「【Chinese Title】」, beside a small decorative English text “【English Subtitle】”. No 3D, no modern neon, no chibi, no game UI, no cheap national-trend style, no watermark, no real logo.
