yeah it is pretty big and there are some areas that need to be cut down sure. But being that it's so early in the development I usually start off making things more open just for the sake of not having get claustrophobic once all the details get added. I believe it's easier to add from world geometry rather than subtract.
I will probably add a mid level platform halfway the long stairs leading to the tunnel with a cut out for cover. here's the latest overview and elevation map.
150/5 :p
