Looks great so far! Reduce your material's ambience to add more impact and mood, put some negative lights in the corners at low intensities. The blinds should be brighter with that much light hitting them...try adding a square parallel light facing them from the outside, move it real close, set it to ranged falloff on like a setting of 5 or 6, then crank the intensity. That should add a glowinbg effect... I don;t know if you can change this but the blinds are too straight. Bend a few of them to make it seem more realistic.
