I really like this HDR. Often people cram on the effects and it looks like something the camera barfed up. This looks pretty damn good. Colors are good, and details are amazing. I assume that you used a tripod? Awesome photo!
There's a place like this near me. They built a modern one in 2008, but up until then we caught the Amtrak at a building from the 1890s. Last time I was in there it was in slightly better condition then this, about the same size, but it still had the old-fashioned radiators, rusty oval door knobs, and molding details that had about five layers of paint on it. Sadly, they probably tore the place down by now.
