Thanks guys, I've tried to get subtle variations into the models. The main vehicle colour is darker that the warriors armour, just drybrushed with the same shade. Similarly, the scourges have more parts of the model painted with the armour colour since they get a 4+ not 5+, and the reavers get very little at all of that colour for the same reason (same armour save, but less actual armour).
Look forward to seeing you there, we've got a 5-player carnage match coming up on the 30th that's the culmination of an escalation campaign, which should be fun. Sadly the following week I'm running a polling station in the election so won't be there (though it does mean a very long, very quiet day so lots of painting should get done!).
I'll be putting this thread to bed for a bit in terms of progress once I've got final pics of the individual units done (see page 1), but don't fear, I have a thread in the distractions board where I'll be updating pics of my Iron Fists marines as they get done (first on the list, 2 razorbacks, a stalker and a vindicator - mechanised lists are so much fun!)
