Escalation Nurgle Bile Trolls (Chaos Spawn) WIP

Here's an initial shot of the chaos spawn I'm working on.  One of these will be added to my 200 point list for Game 1 of my escalation project.  They're made from Forge World Bile Trolls and are on 60mm bases which makes them larger than normal chaos spawn but the models are awesome and I couldn't resist using them in game.  I figure the large size is befitting toughness six anyway :)
I base coated these with catachan green and then sprayed shadow grey and spacewolf grey from above.  Nurgle armies are notoriously green and I wanted to add more colour.  A muted blue will accomplish that plus being an old World of Warcraft player my mind sees blue when I think about trolls.
