That looks pretty good but a tinge too warm for my taste. I set the gray point corrector in Photoshop using the gray trim on the pipes in the first shot and got something I think is a little closer to how it looked.
Edit: For some reason, that tool also lowered the blacks a bit so keep that in mind. This is just a idea
