Wow !
That’s just fantastic .
Thanks for all the crits and comments. I am going to call this one done and move on. Maybe if I can find some good reference I will texture it, but right now I am not sure where to take it.
This is so… 
WOW! You have done a great job!
waow i dig it !
What are your lighting and SSS setup for that last render?
i use myself MR and SSS Skin shaders for my head model but don’t have as good result as you got here. Any help would be very nice 
you can check my thread here http://www.zbrushcentral.com/zbc/showthread.php?t=34938&page=2
that head is absolutely fantastic, the sculpting is great, the textures, the design are wonderful…
my only critic would be that the shadow that hits the ground have to soft edges and since the lighting in the scene is strong maybe the edges should not be that soft…
again wonderful work 
do you use Projection Master to create such detail or do you model it, I’m just curious because in order to model such fine detail without PM you’d need a reaaly powerful computer and I’m kind of blocked by that…
Especially since the undo function is muched diminished on high res…
this is a nice model, good job
