9:16 Vertical Cultural Exhibition Poster Design

Design a 9:16 vertical cultural exhibition poster, overall in contemporary Editorial Graphic Design / art publication visual style. [Theme]: [theme] [Chinese Title]: [Chinese title] [English Title]: [English title] [Main Visual]: [main visual] [Secondary Pattern]: [secondary pattern] [Primary Color]: [primary color] [Secondary Color]: [secondary color] [Date / Institution]: [date institution] Core use of 'diagonal energy' composition, but do not draw obvious diagonal lines directly. First determine a hidden diagonal visual main axis, letting the main visual, Chinese title, pattern, date information, and white space visual weight progressively advance along the same direction. The main visual carries the primary weight; the large Chinese title must participate in the layout, can be offset, vertical, locally cropped, or slightly interwoven with the main subject; the English title, date, and institution information are reduced and concentrated in 2-3 areas, forming a clear font size hierarchy. Each poster uses only one set of secondary pattern language, and make it relate to the theme itself, such as sound waves, map folds, artifact rubbings, plant prints. Do not add multiple sets of decorative elements for richness. The background also needs to participate in the design: use art paper texture, extremely faint pattern remnants, graph paper, specimen information, or material texture, giving white space layers, but still clear from a distance. Overall information density is medium-high, but must have hierarchy: first glance sees composition and main subject; second glance sees Chinese title and pattern; third glance reads English, date, and auxiliary information. Color controlled within 3-4 main colors, creating tension through scale, cropping, overlay, density, and white space. Overall effect: cultural exhibition poster, editorial design, mature print publication feel, rich but not chaotic, diagonal energy naturally present, do not deliberately arrange elements for the sake of 'diagonal'. 4 replaceable case examples: 1. Tide Echo Main visual: black-and-white organic tide pool / mineral forms Pattern: cobalt blue Moiré concentric sound waves 2. City Folded Scenery Main visual: urban pen sketch composed folded observation notebook Pattern: mustard yellow map folds + extremely faint city road network 3. Eastern Vessel Charm Main visual: large bronze vessel Pattern: taotie pattern, cloud thunder pattern, and inscription rubbings extending from the vessel surface 4. Night Flight Among Branches Main visual: old tree branches + black crow Pattern: pale ochre large plant leaf prints
