It looks too perfect to me. There are no scratches on the chrome, and the mirror doesn't seem to be reflecting anything. Also, it's not a great composition, as I can't figure out if we're looking through glass into the room, we're in a shower, etc. It's close, but not quite there yet in my eyes. It's the small stuff that makes things look realistic. They also take 99% of the time. Are you using ambient occlusion? It might help a bit to darken the corners of the room.
