I actually like the bed sheets. The only thing that bothers me is the glow on the ceiling lights. Feels like its too much, but that could just be me. Also, are you using some type of toonshader? Some objects feel like they have a slight black outline around them, especially the lamps. Not sure, maybe Im mistaken. Maybe you can also show different versions, like a render with only the lamps turned on and the ceiling lights off, could be cool and dynamic
Overall it looks great!
