Step 11: Using the small bottom circle as a guide, draw a series of rounded-out rectangles that get shorter as they extend out to create the bottom piece of the Stormtrooper's helmet.
Step 12: Finish up the bottom part of the helmet by using the small circles on each side as guides to draw a line that goes around the middle piece and then meets up with itself. Inside the circles you just created, draw two more tiny circles. Draw two lines on top of each circle to connect with the line above it. These are the Stormtrooper’s lights.
Step 13: To draw the sides of the helmet, draw a line on each side that bulges out at the bottom. Give the helmet some detail by drawing a series of small lines that start near the mouthpiece and recede back.
Step 14: Draw in the earpieces with three lines on each side. The first line is long and resembles the line in step 13. The second line goes right on top of this one and is smaller. The third is smaller still and sits on top of the second line.
Step 15: That’s it! You now have a nice sketch of a Star Wars Stormtrooper. You can stop at this quick drawing for a rough, sketchy look or go for a more finished look by continuing to the step below.
