Step 6: Darken if the top part and use the top horizontal construction line as a guide to draw a band on the Stormtrooper's helmet.
Step 7: Tighten in the shapes of the Stormtrooper's eyes by making them more round and less angled. Draw a small curve in between the eyes to represent the structure of the helmet.
Step 8: Draw a curved line below each eye that almost meets the curve in between the eyes. To the side of this curve draw a series of tiny rectangles as detail for the helmet.
Step 9: Using the bottom horizontal construction line as a guide, draw the bottom portion of the Stormtrooper's helmet. Make the top part a bit wavy and widen the sides to outside of the main oval, then bring it back inside to meet the small circle at the bottom of the head.
Step 10: Darken in the mouthpiece and draw a series of vertical lines inside of it that will end up looking like small rectangles.
