Oh. You wanna know about the extra lip? I'll tell you about the extra lip. Its actually more important than the regular lip, if you ask me. Its cuz the extra lip has the structure to it. It has the depth, the crease in the flesh. That other lip, you don't even have to draw it, if that's all they have. I mean, if you wanna put down a little color to indicate it, fine. Fine, draw the regular lip, but don't come complainin to me when your likeness comes out weak. Look for the depth of flesh on the bottom lip. Look for the shape and the volume, the creases. Tell me about what you see with your marker.
So I was drawing Rupert Murdoch today. He has a great extra lip. He's somebody that has an extra lip in addition to a regular lip that has some volume and personality of its own. Very rare, not so rare in older people though. I'll put up a link to the video I did the sketches from right here(:
