This is a sculpt that I have made all in Blender.
I have make it in 3 step:
First, I have scult alla from a cube:
Than, I have used the Blender Retopo and I have done a more correct geometry.
At the last, I have sculpted again on the new geometry, to have much control the poligon density in difficult areas (Ear, Mouth etc…).
hey … it looks awesome … i really like the texture detailing 
…
might sound like a noob question but how did you do the skin texture details( the veins and bumpy textures etc)??? did you wrap a normal map on to the mesh?? can i please see the normal map?? i have no idea how to make a normal map for my mesh … :no:
It’s only sculpt, the mesh is on 800K face.
For detailing I have use a Free Alpha Brush set.
For the normal map, there are a lot of tutorial in internet, search Baking Normal Map on Google or on BlenderNation.org
Would be really cool to see the full voldemort with his clothes 
(judging by how well you’ve made the head, I suppose the full character would be awesome :D)
Wow! you’ve done some really good job making this head. I’ve got no complaints at all since I probably couldn’t do it any better 
Nice! Keep going!
