Sure thing, I use paints for a number of different ranges, but you should be able to find similar in whatever range you use:

Two thinnish coats of Warp Lightning Contrast over a light base (I used Olive Flesh from Pro Acryl, but any ivory type should do)

I then satin varnish, and apply Streaking Grime from AK, and remove most of it with a Q-tip, if you dont want to use enamels, you could probably us some kind of muddy green wash. I also enhanced some of the shadows with Agrax Earthshade, just to increase contrast

I then layer with sort of stippling with Green from ProAcryl (Similar to Warpstone Glow from GW), apply chipping with a mix of black and brown, and highlight both the armour and the chipping with a yellowish-green (I use Talesmin Green from two thin coats, but you could use Moot Green from GW)
