Overall really well done.
However, there are a few things I personally would've changed. The computers I feel could've been actually built, instead of using a ramp and slapping a decal on. I see you built the towers though, that's nice. It's also quite a bit small for an office building. Other than that, it's awesome.
8.5/10
Edit: After looking through the pictures again, I saw that you did actually build one monitor, but the rest were ramps. Unless, of course, those are typewriters, in which case you have some obsolete equipment.
