In this stage I am on stage 5 of the tutorials. In this tutorial I was taught how to create a symmetry of my face rather then re-modeling the curves all over again for the other side.

There are many ways to clone/mirror the image, by clicking the mirror button on the top of the tool bar I can choose which axis I would like to mirror and then after when I adjust anything it will "mimic" on the other side.

Another way is to click the face and then right clicking the mouse button and selecting "clone" and again I have a choice of three options, Instance/Copy/Reference.

The way I used was I selected the face and going to "Modifier > Symmetry > Flip" to move the other side I click on the "+" button next to symmetry and then highlighting mirror and then start to move the face. Here I would like to mirror the image by allowing the mirror to sit on the nose.
