How to draw the Forbidden City?

The Forbidden City is the most famous building in China. Let me share his painting style.

First draw a trapezoid with curved sides, then draw a flat rectangle below, and repeat twice. The rectangle below is divided into several small rectangles with vertical lines, and then a longer horizontal line is drawn below.

Then draw the trapezoid and the five arches inside, then draw the two sides of the trapezoid downward at the left and right ends of the horizontal line, and draw five arches in the middle of this figure, and the arches gradually become smaller from the middle to the two sides, and finally connect the lower part of the trapezoid with the horizontal line.

Finally, the trapezoidal pattern is painted yellow. Finally, the two trapezoidal patterns above are painted yellow. The largest trapezoid below is painted pink except the arch, and the rectangle above is painted dark green.
