The background objects are looking really nice (in terms of details, color etc), the foreground (the tileset itelf) however - I personally think - need a little bit more details. The light grey areas look slightly boring if used on a lot of space.
Maybe more visible metal plates? You have done that in the background (both section background and deco objects) really really well.
What I mean is also visible there:

However, best looking factory tileset I have seen so far overall. Good job!
