The important thing is to choose simple key points and then estimate where they should be halfway between point A and point B. I chose points like the top and bottom of the circle I drew for the upper skull, the center point of the guideline for the eyes, the center point of the guideline for the lips, the lower curve of the nose, the peak of the chin. This is why it's important to break it down to simple shapes; this is far more complex than a plain bouncing ball, and even with such simple shapes there's still over a half-dozen key points to work with in just this simplified version.
