Carve the cheeks away on either side leaving the first stages of the nose/lip/chin mound.

With Hitty's child-like profile, her nose, lips, and chin all thrust out to basically the same extent, as opposed to a more adult profile where the nose would be more prominent, so it is very helpful to leave the nose/lip/chin sections mostly connected down the center of the face as we carve back the cheeks on either side. This also helps reinforce and protect all three areas until the very end. Focus in this step on carving the level of the cheeks back from the nose/lip/chin area, which should begin to be visible even in profile.
