From there to here

Last week

This week

Big Uncle Earl's jaw is finding form.  The lower lip is contoured to meet the upper lip.  I've smoothed some of the contact points' odd bends and twists. The interior has been smoothed. After it dries, I'll add the tongue.  There won't be any teeth since Uncle Earl will be a candidate for dentures. 

Also, I think I don't make jaws exactly like most folks.  You know, with precise parallel slits on either side.  With the old guy characters, I think uneven contours and overlaps make more interesting and expressive faces.  As long as the jaw opens cleanly, the funny angles add a lot of "character" to the character.
