Design 6 3D Face Images

I need 6 child faces designed, similar to 3D look seen in example at this link. [login to view URL] The link ONLY shows the "Pixar style" of 3D I want. I need a younger face, and face will not be specific to a boy or girl. I do not want a body, just a child's face. The face should look similar to a child that is 3-4 years old. ALL 6 faces will be EXACTLY the same EXCEPT HAVE A DIFFERENT FACIAL EXPRESSION. The faces must look GENDER NEUTRAL. (Not like a boy or girl.) I will give specifics on the expression of the face to winning bidder. Thanks!
