I added some red and sepia Ink washes to all the wounds and open stomachs to give them a dark gory red brown base. I then gave them a coat of gloss varnish and then washed the entire models in a brown and green mix wash to darken them up a bit especially in the recesses. I then did a thin purple wash to get a bit more color variation.  The next step was to paint in the guts and wounds with some Vallejo red, wash that with purple and then go back over it with red... I then realized i was out of pink so I'll have to wait on the guts until I can get to the game store.  

Lastly I hit all the pustule with some yellow to get them standing out and make them gross. I will wash these down a bit next and start working on green highlights.
