Your flash is alot brighter than the ambient light in the room, you could try to shoot with a slower shutter speed, 1/60 and see if that will help. It also depends on how much ambient light you have in the room. Turn on more lamps, etc and shoot at 1/60 and you should have some ambient light in the photo. Also, you could just use your flash for fill-in and use the ambient light in the room for the exposure.
