City Nature Observation Exhibition Poster

Goal: Create a vertical exhibition poster with a handmade silhouette-collage aesthetic for {argument name="exhibition title" default="城市自然观察室"}, combining rock specimen textures, black cut-paper hands, botanical details, and an orderly museum information system. Canvas: Portrait poster, 3:4 ratio, off-white paper background with subtle grain, screen-print texture, slightly imperfect ink registration, muted blue-gray, slate, moss green, charcoal black, and white. Layout: A tall irregular pale blue-gray vertical torn-paper shape runs down the center. Place the main title as huge stacked white Chinese block characters inside this central strip, reading from top to bottom, with a bold condensed geometric style. Around it, arrange specimens and hands in a balanced collage, leaving generous negative space. Main visual elements: Use exactly 4 black silhouette hands: 1 left upper hand pinching a small blue stone, 1 left lower hand cupping a large green stone, 1 right upper hand pinching a dark stone, and 1 right lower hand holding a magnifying glass. Use exactly 14 visible stone/collage pieces: 1 blue textured stone near the upper left hand, 1 pale gray triangular paper-stone under it, 1 blue curved strip on the left middle, 1 large green oval stone in the lower left center, 1 light gray torn fragment at the lower left edge, 1 small dark gray stone near the bottom left, 1 blue polygon stone with a tiny white plant silhouette at upper right, 1 dark hanging stone below the upper right hand, 1 green stone at right middle, 1 narrow blue-gray strip to its lower right, 1 black oval stone at right middle, 1 horizontal dark gray rectangular specimen bar, 1 gray rock near the lower right, and 1 dark blue torn block at the bottom right. Add exactly 3 delicate botanical accents: a small white plant silhouette inside the upper-right blue stone, a fine white/blue plant sprig beside the large green stone, and small black fern stems near the bottom left. Typography and text: Add small vertical side branding on the upper left with a simple mountain-like logo and the Chinese name {argument name="venue name" default="新美馆探索基地"}, plus tiny English text "XINMEI MUSEUM EXPLORATION BASE". On the upper right, add vertical blue text "春季展览" with small English "SPRING EXHIBITION". Near the center-right, add a thin vertical list: "石块 / 标本 / 观察 / 手作 / 记录". Add a short vertical poetic line on the left: "春天从一块石头开始，观察一座城市的呼吸。" Add a small right-side label: "策展 / 新美馆探索基地". Bottom information band: Create a clean white footer separated by thin pale blue divider lines. Include an open day label on the left, the date {argument name="event date" default="05.17 — 05.18"} in large serif numerals with small SAT. and SUN. labels, the time {argument name="event time" default="10:00 — 17:00"}, the venue address {argument name="venue address" default="新美馆探索基地 深圳市南山区怡海大道128号"}, a participation note, and a QR code on the far right. Add a blue strip at the very bottom with small white Chinese text indicating public opening, free participation, and reservation entry. Visual style: Contemporary art museum poster, tactile handmade paper collage, silhouette cutouts, stone-rubbing textures, specimen observation theme, disciplined information hierarchy, elegant but not abstract. Avoid photorealism, gradients, glossy effects, or extra decorative clutter.
