you beat me (I know its not a competition) hands down but as I look through the different WIP and look at the heads and bodies it seems to me that they can never be life like because most people are using a mirror method of some sort. Whether instancing (I barely know what it means) or straight poly mirror; the human head is not symmetrical. If you get a picture of Anybod's face and then cut it in half and mirror the separate halves you get completely different looking people (hope this is making sense) so if one wants photo-realism I can't see how it can be achieved via ANY mirror method,
The difference between the right side of the head and the left side of the head are SSOO different in real life that I can't even imagine going back in after the event to change one side a little???
take it easy and life will be easy
