I got some more houses done over the past week. I used the same technique as my previous post. For the eagle-eyed among you I used a lighter mix of paints (mentioned in the previous post) on the larger house and the original mix of paints on the smaller store. The more I look at it I think the original mix has better contrast and will use it going forward. I also think the big house may need some more rougher (sandy) areas to give it more variation. So in the future I will probably be more liberal with the sand, like I was on the store.
