Civic library elevation poster

Create a vertical architectural poster for a fictional neighborhood library with a shallow barrel roof and a long shaded colonnade. Place a precise front elevation in the lower half, drawn with fine graphite and a few soft charcoal accents. Behind it, add one large pale-blue circle and a smaller muted clay rectangle, keeping the shapes separate from important building edges. Use warm uncoated paper with subtle fiber texture and wide margins. Suggest scale with one small tree and two simple human silhouettes. Include only the heading CIVIC LIBRARY near the upper left. Avoid decorative handwriting, invented measurements, and dramatic perspective distortion.
