4. Removing the edges from the lips has left us with two stray vertices, shown in Fig-
ure 5.43 at the top. Weld these vertices to the ones closest to them, smoothing out
the upper lip ( Figure 5.43 , bottom).

Next, we will examine Kila's eyes before moving on to the rest of her head. They are quite
round, but we don't actually need this amount of detail.
1. We can get away with collapsing the edges highlighted in Figure 5.44 (left), be-
fore moving the remaining vertices to reshape the eye as shown in Figure 5.44
(right). By doing this, we'll regain 18 quads, or 36 polygons.
