4. Add Textures
Add clouds in the sky above the barn with irregular shapes. Give texture to the barn door with vertical lines. For the barn roof, use angled lines that follow the shape of the roof. Put crosses in the windows for windowpanes. Finish the top of the silo with four curved lines. Give texture to the tree trunk with broken lines. Show the reflections of the tree and fence on the water with wavy lines. Add a few feathers to the duck with tiny hooked lines.
