The check point looks great Grunt, good work!
A little more detail on that larger wall at the end of the canyon would be good though, in my opnion. Even if it just some Imperial insignia.
Yeah, the wall is just there right now so I know where to line stuff up at.
I build my maps in different parts, and put them together like a huge lego set once a part is done, so I can edit areas easy and not have to look at messy 2D views either. The wall will get updated once the city is on it
