Step 16: Use the initial shapes as guides to draw the rest of Green Lantern's head. Follow the basic path of the guides as you darken the line. The line on the left side of the face near the eye should bulge out more for Green Lantern's brow and cheekbone.
Step 17: Darken the lines under the head for Green Lantern's neck. Draw a couple of lines in the middle for the neck muscles and a line near the jaw for the top of his costume.
Step 18: That’s it! You now have a nice sketch of Green Lantern from Justice League Unlimited. 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.
Step 19: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Wait for the ink to dry, and then get rid of every pencil mark with an eraser. You now have a finished inked drawing of Green Lantern! You can stop here or go to the final step to complete your Green Lantern drawing.
Final Step: For a completely finished Green Lantern drawing, you have to color it. You can use markers, color pencils or even crayons! Color his skin brown and his eyebrows and goatee black. His eyes are yellow-green, and his costume is dark green. That’s it! You now have a completed drawing of Green Lantern from the Justice League Unlimited animated series.
