3. Connect the Lines
Draw two vertical lines under the arch. Connect them at the top with a horizontal line. Add a second line to each of the slightly bent lines as shown. Draw an upside-down Y in the top tier with double lines. Divide the rectangle near the center of the tower with a double horizontal line and a single horizontal line.
Connect the upper double horizontal line to the line above it with an angled line. Add two short vertical lines to the single horizontal lines to connect them to the lines below. Continue double lines below the second horizontal tier. Draw double angled lines below the third horizontal tier. Use curly lines to add shrubs.
