I would suggest you start with the eyes and nose, that is the most memorable area of a face. Then work out to the cheekbones and down to the mouth. Working with default morphs is ok to start with, but eventually you'll need to work with magnets or an outside app to create new morphs. Theres a yahoo group dedicated to this subject, give it a look if you need help or advice.
