Here are some painted Kroot for you. Used Catachan Green for the main green color with Camo Green and Rotting Flesh for subsequent hilights. I used a Devlan Mud Wash over all the Catachan Green areas, then highlighted over top.
The brown bits are Bestial Brown and Scorched Brown with Snakebite Leather highlights. Metal portions were Boltgun Metal with a Badab Black/Water (half and half) wash. I then highlighted with Chainmail.
