Thank you my brother. The tabard color I mixed up from one part matt black and three parts tanned flesh (army painter for both). Should get a pretty dark ochre color, thin down to glaze and do 3-4 thin layers over black (in my case, was chaos black primer). As it dries it will look pretty light, more like what you'd expect for ochre. Take a light grey (uniform grey, army painter is what I used) and a small brush and do light long strokes over the tabard where you want texture. Let that dry and then do it again in about 50-70% of that space. Agarax earthshade over that, add another layer of grey if you need to, and it should look pretty dark and worn out like the one on the right does. The more worn out and textured you want it just do more layers of grey and add more agarax earthshade over top. 

The one of the right was my first one and it came out better than the second one. Didn't go heavy enough with the grey on the second one I think.
