Step 6: Finish the Drawing Delete the regions of the head that are covered with hair. Then, draw over your lines with a darker pencil stroke or a black pen/marker to intensify them. Then, using black, fill in the lashes and brows (or dark pencil shading). You may add hints of individual eyelashes when adding the black fill/dark shading. To finish the image, add some shading to the lips and hair.

Include the tongue and teeth. It's fairly easy since you just need two lines for this. To create the tongue, start at the bottom of the mouth and draw a line that bends upward. It should begin at one end of the mouth and work its way to the other. Draw a line that bends downward at the top of the mouth to represent the teeth. This line, unlike the tongue, should not come into touch with the sides of the mouth
The last thing I remember is that the plot revolved around figuring out who killed the best friend's sister with the help of the witch's magic, the protagonist becoming a skilled hunter? (I'm still not sure what they were called), and some tension building between the best friend and the protagonist. That's it!
