When the sphere was ready I made a cut in the middle of the mouth and rolled up the wire mesh to create the 'lips'. I rolled up some more wire mesh and attached it above the mouth to form eyebrows.
Again, make sure the surface is smooth and no loose ends are hanging out.
To let some light shine in to his eyes I lodged two rolled up pieces of cardboard in the wire mesh directly behind the holes in the shells. This way I can pack in the cement and keep an opening that will go all the way to the fire.
