I think Archangel is right, the movie makeup screenshot is the most accurate one to follow. Remember that the face isn't getting rigged to JKA's skeleton, it's getting rigged to a custom one. Facial expression will be modified by mood, and compensating for the model will lead to distortion. You need the face to be absolutely relaxed as possible otherwise you'll get the JA effect of the face being distorted by two different emotions being played at the same time.
