I almost finished this head and this work is my first serious project on 3D.
I have a helmet and a part of armor to bild until this work will be finished.
So,what do you think?
(and if you want to see some other stages of developement,check this link:

And a less shadowed image;) 
really nice modeling and the texturing/shader is so realistic!
Nice job.
Nice modeling–love the expression.
Thanks a lot!
I must say I’m amaized I could model such details(because of 1.7 million poligons of the most complex version of the model) on a sistem with an Amd Athlon 700Mhz & 256 MB RAM!!!
Z-Brush just ROCKS!!! 
nice shader
you could break the symmetry in the fat area/wrinkles
