5. Add Detail to the Windows
Add bars to the front cab window and a squared shape to the back window. Sketch a whistle coming off the bell closest to the cab. Draw a rectangle between the front and back wheels and some other detail shapes by the wheels to start forming the piston section. Add a wedge on the scoop and a rectangle on the front of the car. Add a few more shapes for details on the side of the engine.
On the next page, we'll work on the piston sections.
