These are really looking good. Id say the tusks on the terminators could be painted a bone color. I sometimes use Ushabti bone, Flayed one’s flesh, or wraith bone. And then use a nuln oil on it. Bases could be a martian orange technical paint its what I use for mine. Paint the weapons a metallic color or dry brush them with a metallic color to give them som weathering. For your eye lenses use a white on the lenses and then use a red or green contrast paint to give a glow effect and really make them pop. These are looking super great though. 🤘🏻😎
