Over the past couple of days, I have been painfully applying all the teeny weeny fiddly stickers to my Kato and Tomix N scale structures. Wow, how annoying they were! Some of them are so small but they really make a major difference to the look. So far that is all I have done to the buildings, I still want to add lighting, weathering, people and furniture.
Pretty much just built and randomly placed all the buildings.
