Environment Rough Sketches

So here're more conceptualization of the abandon/submerge metropolitan. Did bird eye view of the metro so I can get the feel of how big this place should be.  Also, I'm trying to capture the lives of the residents.  Still rough ideas, so probably next step will be refining those ideas.

I wanted to make a place where drifters and others can gather for pretty much anything. An epicenter for trade, supply, news, entertainment, etc...  And speaking of drifters, I'm working on concepts for other drifters along with this metro. So I guess I'll post that next round.
