Step 11: Use the initial triangle-like shape inside Charizard's head as a guide to draw the eye. Darken the shape of the triangle and draw a line above it for the brow. Draw a small circle inside for this Pokemon's eyeball. Add a big dot inside the eyeball for the pupil.
Step 12: Draw Charizard's horns on top of the head by following the basic path of the short guide lines. Make the horns thicker at the bottom. Draw the top and right side of the head too.
Step 13: Use the initial shapes as guides to draw the left side of Charizard's head and top jaw. Follow the basic path of the guides, but make the shapes more angular.
Step 14: Darken the lines under the head to create this Pokemon's lower jaw, but make these angular as well. Draw a couple of tiny circles on the tip of the top jaw for Charizard's nostrils.
Step 15: Inside the shape of the lower jaw, draw a triangle-like shape for Charizard's tongue. Draw two tiny triangle-like shapes on the top and bottom jaw for the pointy teeth.
