Time to hide behind the sofa...
Zbrush speed sculpt of the 'Davros' character from Dr Who, in his 80's incarnation which I remember from my childhood.
Sculpted in Zbrush, textured in Substance Painter, and finally rendered with V-Ray in 3dsmax.
As these "speed" sculpts go this one got a bit out of hand, and I probably spent a day and a half fiddling around with it in the end.
