Well, from your screenshots I have to say this. First, I really (truly) like the oddly rotated buildings. But, what would we be without dem issues?
First off, I would replace your two mirror-rotated cars in the first screenshot with just one. I would also work on expanding out the chokepoint in the middle of the map. Right now a player can only go through the hill, or they can try and go around the sides, but each way is very easy to block, so I would advise opening it up with potentially more buildings in order to slow a quick takeover and hold of the middle.
