Some concept illustrations I did for Sarah Connor Chronicles showing what to do if a terminator comes after you: shoot him/her in the face with a shotgun. The actor was filmed with prosthetic make-up, and a patch of greenscreen to be replaced with CG.
A matte painting of a post-apocalyptic nuclear power plant from Terminator: The Sarah Connor Chronicles which I did at Entity FX. The plant was an actual filming location, but I modified it by painting decay and battle damage over it.
Here is what the original footage looked like... And here is the final composite, featuring a CG human-killing robot by David Alexander.
