The way the curtain is defined is what I like best in this shot. Great lighting in the top left corner, and also on the metal parts on the box. Strong and simple, and maybe worth simplyfying even further. The lighting quality in my view gets lost towards the bottom right where it looks like you had to dodge quite a bit to get more or less even light. You could do away with this, and I am also not sure if the wall adds enough to keep it.
A simple comp with simple objects. Since there is no context to help out, they seem to work together to create some mystery. I wonder what the little knob in the bottom right corner is.
