Inspired by the sci-fi classic Terminator 2: Judgment Day this is an excellent Terminator T-800 Endoskeleton Custom Minifigure. The Skull is a heavily modified skeleton head by Guy Himber, while everything else is hand sculpted by Sander using ProCreate putty rather than Greenstuff.
The T-800 has been nicely painted including the eyes and I really like the weapon. He has been placed a display base which has a sculpted skull, and really showcases this minifigure.
Overall a very nice sculpted custom minifigure!
