Now the last thing you'll want to animate is the eyes and eyebrows, to give your character some expression. The procedure to animate the individual parts should be old hat by now, as many times as we've done it in this lesson alone. You've got many separate pieces; I'm going to start with my eyebrows first, working on those individually and raising and lowering them to add a little nuance to his "speech". Then moving the eyeballs themselves, and the eyelids last. You'll notice that I put his hair on a separate layer, and then made it invisible (after extending its keys out to the length of the entire animation) to make it easier to select and work with the facial features. Don't forget to make everything visible again before going back to your main scene.
The great thing about this is that on the facial features, the movements are fairly basic and you can just copy them where you need them, once you do it once. Try doing a full animation of an eyebrow lifting and lowering, and then just copy the keyframes you need where you need them. The same can be done with all of the rest of the facial parts. This makes doing detailed animation a little less tedious, and the motion comes out smoother.
