First off, let me say I love the rest of the update, and I'm fully aware this is WIP.
However there are some problems here. The roads are much too wide, at least 2-3 times as wide as they should be, judging by the scale of the train. In general, trains dwarf crossings, not the other way round. Period roads in the countryside would be narrow, usually around 12-15 feet wide, designed so it is possible for two oncoming cars to pass each other with care. Try placing a car on one of the roads and having a look at the width. If it isn't possible to place at least 4 cars side by side on those roads, I will eat my metaphorical hat.
Hedges are also a problem, you clearly need a hedge type of vegetation that can be placed along the sides of the road, because achieving a satisfactory look with individual bushes is going to become prohibitively expensive in terms of numbers needed, and at the moment the hedges look like individual shrubs placed at intervals along the side of the road.
To end my comments on a positive note, the way the trees and landscape work together at a distance (on the hills in the background) is fantastic and bodes well for the way the SOW will look from altitude
