Hi, and a delayed welcome from me. Some admin guy, I have been of late!
Love this shot.
It is evocative, another time and place and nice exposure. To my eye, you seem to have captured everything form the deep shadows of the radiator, the subtle shadows under the desks, mixed with floor reflections and the expected 'blow out' of the desk top, given the angle.
The give-up (that you have no control over) is the electric column oil heater
