Know this is Stupid, But just some caravan, some Caravan guy and a Building and some dead trees is boring to see, you should add Green Trees like in VC, and some other stuffs.
Well, at first I though this is a waste of time, but the part of the caravan appears with the caravan leader, could give a better feeling to it. Like you see the whole caravan appearing, let's saying moving into the town, or going through, and the leader staying at it's spot, before departure, the same, whole caravan comes from garage and departs towards the exit grid. This should be generic.
Needs some cart animations though.
