Create a cultural event art poster with an East Asian retro hand-drawn aesthetic, combining the visual language of independent cultural exhibition posters from Japan and Taiwan, vintage picture-book illustrations, traditional graphic printing, and experimental editorial design.
Visual Concept and Composition
Create an imaginative miniature world centered on the theme. Through changes in scale, blended forms, or surreal combinations, combine everyday objects, architecture, plants, natural landscapes, and people into a unique and complete visual metaphor.
The main subject must have a striking large-scale form and a clear silhouette. Organize the composition through surrounding, interweaving, layering, partial corner placement, or winding paths.
Include rich and meaningful details of everyday life within the main subject, while preserving natural negative space around it. The image should have strong graphic recognition from a distance and reveal interesting stories up close.
Hand-Drawn Style and Color
Use free, slightly irregular hand-drawn ink lines combined with two-dimensional flat color, selectively detailed linework, and artistic forms.
Lines should vary naturally in thickness. Architecture, trees, and people may be moderately exaggerated, asymmetrical, and slightly naive. Some forms should use dark outlines, while others should be built directly from solid color blocks. Avoid mechanical precision and uniformity.
Use clean, warm ivory-white paper as the background, paired with retro natural colors such as botanical green, lake blue-green, terracotta orange, mustard yellow, and charcoal black.
Choose 2–3 main colors for each poster and use one striking accent color to establish the visual focus. Colors should be rich and evenly flat, retaining an extremely subtle traditional print texture while avoiding heavy grain and excessive aging effects.
Typography and Editorial Layout
Use a bold Chinese main title with expressive hand-painted strokes, combined with a retro English serif typeface, prominent date numerals, and refined small-size event information.
Adopt an asymmetrical, rhythmic editorial layout that allows the text and illustrations to surround, interweave, obscure, or spatially echo one another, rather than simply placing text over the image.
The title, date, venue, and event description should form a clear information hierarchy. All text must have real meaning and create a complete, professional cultural event poster.
Overall Quality Requirements
The image should have the original artistic character of a mature independent illustrator, combining playful hand-drawn charm, vivid flat graphic colors, surreal imagination, and professional typography.
Maintain a consistent series aesthetic while allowing different themes to have their own compositions, color schemes, and visual concepts.
Avoid generic children's cartoons, 3D miniature models, CG rendering, photorealism, complex gradients, overly polished commercial illustrations, random decoration, meaningless text, four-point starbursts, and templated layouts.
Produce a complete, refined, collectible-quality 9:16 high-definition vertical art poster.
