Step 6: Tighten in the shapes of Spider-Man's eyes. Using the triangles as drawing guides, round out the triangle shapes, especially the bottom part. Also, make the outlines thicker and darker.
Step 7: The web design on Spider-Man's mask is a bit tricky, so this section for how to draw Spider-Man's mask has been broken down in a few steps to make it easier. Draw a series of lines on the top part of his head – eight to be exact. Draw two on either side of the vertical construction line that begin where the two construction lines meet. When drawing the other four lines, make them smaller and draw them on the sides of his eyes. Notice that neither the horizontal nor the vertical construction line form part of the webbing.
Step 8: Draw similar lines on the bottom half of Spider-Man's face. On either side of the vertical line, draw two lines that begin where the construction lines meet. Draw four smaller lines on the side of Spider-Man's eyes.
Step 9: Now draw a series of wide curves that connect the lines you just drew. Start out at the top of Spider-Man's head and end just before the point where the construction lines meet. Draw five curves from top to bottom.
Step 10: Do the same thing for the bottom part of Spider-Man's head, but this time draw the curves beginning at the chin and go up toward his eyes. Draw series of about four curves for the bottom part of his mask.
