Just cover it in a combine cover thingy (I have no clue what its called). Think HL2:Ep1 when Barney takes down the shield.
The inaccessible house that you added; the windows are too low down and the roof doesn’t follow the angled corners.
Hmm, you’ve got a nice ‘outskirts of the city’ feeling going there. Expand on that.
You need to remember that even an inaccessible building would have an interior; so you need to accommodate for that in exterior features and scale.
Fixed the windows. And I really need to learn how to make roofs. My roofs suck.
I have most of the map sketched out already on paper, I just need to commit it to Hammer. I think it goes along nicely with the outskirts idea.
