Step 5: Teeth, Eyes and Ears
Teeth: Take a a little worm of off-white clay and put it in the mouth. Make some indentations of where the individual teeth separate and detail this out. After you close the mouth again, you won't have much of a chance to rework the teeth without disturbing the rest of the lips.
Eyeballs: Make some round bits of off-white clay that are equal in size. I made about six to be sure I'd get two close enough to the same. Then, if you're using polymer clay, bake them before putting them into the sockets. Now, using small bits of clay, create the upper and lower lid.
Ears: Now that everything is close to finished, attach the ears. I'm terrible at ears. Use references.
