As you can see with the colour of the montage wall, they are very dark and purple which suits the office
Here we you can see the montage wall. Different alpha channels have obviously been used and these images are changed with different translucencies and more darker colours to connect with the rest of the space
I also changed the texture of the floors to a concrete material that has been darkened. I also increased the intensity of light on the desks and tables. But i think it is too bright and not reasonable for people to work on

One thing i notice is that there is a gap in the side of the stairs in which my avatar regularly falls down as well as it just looks unfinished with this gap. Therefor, something that connects with the office should be created. May be a montage wall of images/textures of the different journals.
