Urban Decay, in HDR

I had been on a HDR spree a while ago, and I was going back over my archive and noticed a nice little theme of "Urban Decay" among the shots. I know it's kind of a cliche to do urban decay photos in either black and white or HDR but anyway! There seems to be an unintentional blue theme going on too! Here's three shots from the collection.

Taken with a Fuji XE-1 and an 18-55mm. HDR Processed in Photomatix Pro and finished in Lightroom using Quicklux.
