For the heads of the ninjas, I used the Ellipse Tool, and for the body of the ninjas I used the Rectangle Tool and the Rounded Rectangle Tool. I made an oval and a circle, then I subtracted from the shape to make the faces of the ninjas, and used the ellipse tool to make the eyes. Around the head and body I added an outer and a inner stroke to give the bodies a bit more shape. Then I colored the ninjas with colors of my choice. I then made them weapons, using shape tools and more strokes. I also positioned their arms and legs to give them striking poses.
