I don't paint a whole lot of terrain, but the Skaventide boxed set for Age of Sigmar came with some ruins. The bottom trim is a darker shade of blue because I accidentially selected the wrong paint and didn't figure it out until I was halfway finished. At that paint I was like, "Eh, whatever."
I used some AK Interactive streaking grime (oil based) to create some of the streaking effects you see below. They're a bit subtle, but you can see it on the lower photo better than the top. I'm thinking about using some of my Dirty Down moss effect on the bottom, but I'm undecided.
