Gabriel , that is a good question you asked there. Now , IMHO , you cannot really say how you are going to sculpt a mouth unless you decide beforehand what the face's expression is going to be. You know , every action has a reaction and this goes for the face too. If the face has a smiling expression , it will reflect on the cheeks and so on. So after deciding what looks you are going to give to the face you handle the basic features taking proper care for proportions ( very important ) , and you go from there. I suppose , many , like me would play around with the putty until all looks the way it should. I would like to know what Quang has to say about this. I will definately learn something. Quang take notice pls.!!!
