Here you can see a new Model I’ve created some time Ago. Originally it was sculpted. Later I created a new Mesh, and added the facerigging. It is far away from perfect, but I hope you will like it. Also I want to publish the .blend File. You can use it, and learn from it. Create your own ShapeKeys if you would like to, or just create some nice Animations. You can use it for learning, but not for commercial works.
Here is a youtube link where you can see, what is possible with that model! I hope you will like it!
The head has about 1000 Faces. Details are baked down into a normalmap. Most of the deformations are done with Shapes. A few with weightpainting.
It also runs in the Game Engine.
So take a look at my blog. You can find the Blendfile there!!
