I would have recommended doing something more unique. It's pretty obvious that you just followed the 3D motive tutorial and created almost exactly the same pieces with pretty much the same look. The first thing I thought when I saw your screenshot was "isn't that just the 3D motive scene?".…
For learning use and modeling of modular pieces i think it's great. But it would be sooo simple for you to break this up to your own layout, own camera angel, own style (still bricks and broken windows), own texture style and so on. This will sting an employer in the eye who have seen the tutorial, or just the presentation…
