a few problems

at this stage a few problems occur which delayed me in progressing with the project further. once i had put the back of the head onto the front, i realised the lips had some how managed to get distorted, and needed to be mended. however, the amount of vertex had increased and this was impossible to correct. the only way i could correct it was to take the front off the back, and attach a back from a previous document.
this picture demonstrates how far i had got before i realised the lips were wrong.as you can see the lips are correct in this picture

as a consequence of not doing the sphere process again it did mess up the symmetry on the head, so it was no longer there, and that is one of the reasons why i could only get so far. if i had more time, i would have had to do the back of the head again, and this would have allowed to go further with the head.
