It's a fairly good office from what I can see. The 2 main things I would adjust, is to use darker floor boards or a patterned carpet on the floor. The other is to place a suitable scene outside the windows. The following asset from Stonemason would work like a charm for achieving that.

Coupling the props from the asset above outside the window and using an appropriate HDRI, will make a world of difference.
There are many fancy looking building assets out there, however many of them render horribly due to the scene complexity and the light sourcing. If you have a high end video card and let a single image render over night this doesn't present a problem, however with my hardware I would prefer a more optimised scene.
If you take a look at my strip club renders, the building scene I have is incredibly simple. The bling factor comes from having the Urban Future 5 asset out the window. Due to the simplicity inside, it renders way faster than any of the other building assets I have.
