Attaching the ears to my model.

I have had a lot of trouble trying to attach the ears I created to my models face, I managed to attach the ear to one side of the face and then I tried to delete half the face and use the symmetry modifier to complete it, however once I added the symmetry it would not align properly and for some reason I couldn't get it to join symmetrically, I asked several people in the group for their help and it seemed to stump everyone, I tried changing the centre point of the head, I tried symmetry on the other side of the head, however nothing seemed to work.
I finally decided that I would re-start the process of adding the ear and add the symmetry tool to specifically the ear only, and then I could start cutting and welding the ear on and both sides would be identical, I managed to get this method to work and this is how it turned out.

This is how I added the ear, I imported the ear into the head file and placed it just away from the position I wanted it to sit, I then applied the x-ray tool so that I could see through the ear and to the side of the head and this allowed me to cut in vertices which would align roughly with the vertices of the edge of the ear, once this was complete I then began to target weld the vertices of the ear to the head.
I had to play around with the shape of the ear once it was on the head by scaling and rotating specific vertices to give a more realistic shape to the ear, as it was modelled flat so therefore did not have the right characteristics of an ear.

When the whole head is smoothed using the NURMS smooth I am very proud of what I have achieved.
