Major Project - Blendshape Tests

I have roughly made all the blendshapes today, some are pretty ropey, but I still want to see how they effect the mesh once rigged. I enjoyed doing this, but have to say, trying to model faces is a real challenge. The next stage is to try and figure out how to rig these in. I also need to sort the file, as 5 of the faces have the incorrect background.
