Urban Buildings - Can't have too many of these eh?

So in digging around for pics to post of some of my older buildings, I am really starting to see the progress of my building skills, and more importantly I am seeing all the little ways I would do it differently/better now.  That gives me hope that there is in fact progress in my goal to build better and more dynamic terrain.

These pieces I built over a year ago and they were mostly just experimenting with foamboard and corrugated cardboard.  I wanted a construction site feel to these pieces and this was the first time I had ever played with the wire mesh.
