Giving depth to face

With the flat shape of the face outlined it was a case of adding depth to define facial features, to do this I had to convert the object to an 'editable poly' allowing me to see the vertex's. I had to go through and pull out the individual vertex's until the aligned with the side reference plane. With the outline of basic topology on the side of the face it was easier to line up the points correctly.

Having added the correct detail a symmetry modifier was added to mirror the other side of the head, this meant that changes made to one side would be reflected on the other. Here is what the head looks like to this point.

As you can see I have made a mistake in my topology causing there to be a pinch on my cheeks, this was a major problem but I managed to fix the problem using the options in the editable poly tool bar.

Here is the corrected face.

As you can see the dimples have gone by adding in another polygon connecting up the broken line. Also the face isn't wide enough at the moment but with some slight alignment it has been corrected which will be seen in other screenshots.
