SLW45, Quaralane, Java, and TRM: Thank you! I too love happy accidents!
Myke: The color is a custom mix. Here is the recipe: 20 drops of Tamiya XF-14 J.A. grey, 9 drops of Tamiya XF-14 Sky Blue, and 3 drops of Tamiya XF-13 J.A. green. I then went back and dry brushed the roof with the J.A. grey.
It was a fun build, and I will build another one soon.
Solander: Thank you! I do have reference photos of bushes growing out of the base. Not moss, but bushes. So you read my mind, I am going to do a bit of hand painting and put a bit of a bush there to cover it up.
I will have an update sometime this weekend, work kicked me this week.
