Well since nobody has done this I may as well post my practice one. I usually just attempt them off line and then delete them. The missing face in the middle I cloned so there are now two of them!! If it is awful I would rather someone was honest as I know they can look different on the web.
As you say the face in the middle had to be cloned. In cases like this I clone bit from several different faces to make a composite (and hopefully different) face
