Part 4: Modelling the head (continued)
Then select the nostril edgeloop, and extrude it inside the head, so that you dont see the end of it.
Extrude bottom edges of the nose to the lip edge.
Then extrude the same edges again, now to form a part of the lip.
Now extrude the whole lip, the lip should be one continuing loop.
Create (extrude) more polys around the lips, and chamfer the lips edges abit. Leave the chamfer wider on the lower lip.
