Black orcs again

Here's a closer shot of the paint chips I'm doing on the black orc's armour. You should be able to see the tin bitz on top of the rust brown. A little bolt gun metal will go on top of this to look like fresh scratches. I'm using an old nylon brush that is all curled up, so if I get the right amount of paint on it I can get the randomness by pretty quickly. This helps get the unit done faster, but if I was doing a single character I'd do it with a fine brush and be a little more purposeful (rather than random).
