City Nature Observation Exhibition Poster - 1

Goal: Create a vertical exhibition poster with a handmade silhouette-collage aesthetic for 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 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 05.17 — 05.18 in large serif numerals with small SAT. and SUN. labels, the time 10:00 — 17:00, the venue address 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.
