If you're working with paper and pencil, either lightly erase the sketch to lighten it, or use a piece of tracing paper. If you're on the computer, drop the opacity of your underdrawing to about 30%. To begin the body, draw a rounded rectangle in the center of the chest (and draw a small tab for the car emblem). Next, draw a pair of rectangular "wings" out from both sides of the previous shape. Add a smaller diamond shape beneath the chestplate.
