Here's some close-ups of some of the face variations that can be done with M3Revitalised. The one on the left is with the David Morph of HdMichael3 set at -1. David morphs can be added after that for exact head duplications of David characters. The other faces automatically come with the M3R package. I think they can go from very realistic to Anime fairly easily depending on the textures and clothing used.
