It's really not a bad setup. Only a couple of things that I can see. Everything looks a little to sharp edged. For instant, the corners on the bed should be softer (more rounded). The room just looks hard. The texture on the back wall behind the bed looks to be stretched to the point of blurring. You might try tiling it vertically with mapping. I think you've done a really good job of laying it out. Keep up the good work.
