It was an idea someone else had used on another forum I use, for the marines. You just slice across the top of the visor level, then into the bridge of the nose and carve it out to shape. The terminator is on it's version 2.0, at first I just cut a slit through the eye lenses but it was only a couple of mm thick and didn't look right, so in the end I just pretty much cut off the nose up and levelled off to give the fuller faced effect. I'm really really pleased with how the visors turned out, they just have a really cool glow to them. As for the masterchief look, it was by accident but I quite like the similarity. Makes them stand out from normal SM's without having to do anything drastic, which of course can be saved for the good stuff.
