The method including generating a second sub-shape of a second shape that corresponds to a second expression of the face, wherein the second sub-shape corresponds to a second portion of the face. The method including modifying the first sub-shape. The method including generating a combined shape by combining the first sub-shape that is modified and the second sub-shape using an editing application. The method includes applying a correction to the combined shape to align relative portions of the combined shape with the first shape or the second shape.
