I like to look at detailing rooms in a very logical way. For example, if you were to have pipes running across the ceiling, then think about what their purpose is for. Not in terms of 'it puts detail in the room', but rather 'these are pipes for channelling exhaust water from the machinery in the connecting room'. Once you've established a purpose for it, you can also look at whether or not its placement makes sense. Again, to use the pipe example: 'do these pipes logically flow on from that machinery in the connecting room and do they end correctly?'.
This doesn't mean that you need to limit your creativity, it just means your creativity needs to make sense, given what you're designing.
Looking at your screenshot, a few things stand out:
1. Why are the diagonal cross-beams so close to the wall? Support beams are generally there to support weak areas of a structure: are you saying that the weakest part of the structure is the rather large, solid brick wall? To me, if this were a poorly designed building, the beams would be further away from the structural safety of the walls.
2. There are a fair few electrical cables heading towards the large pipe in the ceiling: what are they for?
3. Similarly, there's a fair few large capacitor things hanging on the wall: what are they powering? Why are there so many?
4. The three spotlights: what are they illuminating? If they're lighting up the computer panels, wouldn't it make more sense if they were directly above the computers? If a person stands in front of the computer, they block the light from those beams, making it useless.
5. What are the posts for? The times I've seen posts spread out like that is simply to prevent vehicles from entering an area. If they're to prevent people from passing, then they need some kind of chain between each posts, but in an area such as this, it would seem out of place.
Please don't think of this as me bagging out your screenshot: there's potential there, but you need to sit back and have a good think about it.
