hey, it's quite difficult to say really if there is no reference to compare thing to. To me it looks like some of the objects are out of proportion.
I'm not really a fan of the lighting either. I would say the viewer would not know which direction the lighting is coming from. I think you should have the window that is in shot as the key light, or you move the camera so the off screen window is in shot.

Maybe also think about setting up some other angles. Try a couple of close ups of some detailed areas like around the drawers, window sill etc.
