Urban Nature Observation Exhibition Poster

Goal: Create a vertical exhibition poster with a handmade silhouette collage aesthetic for , blending rock specimen textures, black paper-cut hand elements, botanical details, and a disciplined museum information system. Canvas: Vertical poster, 3:4 ratio, off-white paper background with subtle grain, silkscreen print texture, slightly imperfect registration, color palette using soft blue-gray, slate, moss green, charcoal black, and white. Layout: An irregular light blue-gray vertical torn-paper shape runs through the center. Stack the main title as huge white Chinese font within the central band, arranged from top to bottom in a bold compressed geometric style. Distribute specimens and hand elements evenly around it, leaving ample negative space. Main visual elements: Use 4 black silhouette hands: the upper-left hand pinches a small blue stone, the lower-left hand holds a large green stone, the upper-right hand pinches a dark stone, and the lower-right hand holds a magnifying glass. Use 14 visible stones/collage fragments: a blue textured stone near the upper-left hand, a light gray triangular paper stone below, a blue curved strip in the middle left, a large green oval stone in the lower-middle left, a light gray torn fragment at the lower-left edge, a small dark gray stone near the lower-left corner, a blue polygonal stone with a tiny white botanical silhouette at the upper right, a hanging dark stone below the upper-right hand, a green stone in the middle right with a narrow blue-gray strip below and to its right, a black oval stone in the middle right, a horizontal dark gray rectangular specimen strip, a gray rock near the lower-right corner, and a dark blue torn piece at the lower-right corner. Add 3 delicate botanical decorations: a white botanical silhouette inside the blue stone at the upper right, a fine white/blue plant branch beside the large green stone, and several black fern stems near the lower-left corner. Typography and text: Add a small vertical brand mark at the upper left, containing a simple mountain-shaped Logo and the Chinese name , plus tiny English text "XINMEI MUSEUM EXPLORATION BASE". Add vertical blue text "Spring Exhibition" at the upper right and small English "SPRING EXHIBITION". Add a slender vertical list at the middle right: "Stone / Specimen / Observation / Handmade / Record". Add a short vertical poetic line on the left: "Spring begins with a stone, observing the breath of a city." Add a small label on the right: "Curated by / Xinmei Museum Exploration Base". Bottom information bar: Create a clean white footer separated by a thin light blue divider line. On the left include an open-day label, date in large serif numerals with SAT. and SUN., time , venue address , participation notes, and a QR code at the far right. At the very bottom add a blue band with small white text noting public opening, free participation, and reservation entry. Visual style: Contemporary art museum poster, tactile handmade paper collage, silhouette cutouts, rubbing textures, specimen observation theme, rigorous information hierarchy, elegant but not abstract. Avoid realism, gradients, glossy effects, or unnecessary decorative clutter.
