I found this painting extremely tough going because I had the huge obstacle of a beam in the way exactly where the characters face would be. My only option was to try and make the face look as natural as possible from an eye-line perspective.
Another obstacle for me painting this was the lack of images of 'The Terminator', I ended up gathering as many stills from the film as possible as well as using a model to try and recreate as accurate as I could.
