These have been in storage for a while now, it was back in 2011 that I gave the models a basecoat of Humbrol Sea Grey spray paint. I had earlier, drybrushed the Broken Aquila, and then used the same technique on the Space Marine Statue and ruins.
These are the ruins.
As I mentioned in my previous post on the Broken Aquila, I was originally going to keep the whole model grey, but I am now thinking I might add more scenic and foliage and rather than have it as a recentl ruin, have it as one that was left some time ago and nature has over time grown around it. The Imperium has been around for ages and so it still fits the fluff. The statue certainly looks like it is aged rather than damaged as part of a recent battle.
