Needs a slight bit more clutter on the table. Half eaten sandwich or a broken object something anything( small teddy bear with a eye pulled off laying on table. The vase does not look like it is sitting on the table. Fix it. It may be but fix it anyway. The sink needs a bit of a bump. Maybe fill it up to overflowing with water. Put some water on the floor. You could have the perfect cool render if you rendered with volumetric light and add dust to the light beams. ( Really slow render) So watch out but it would look really cool. It looks really good right now though but you did ask :)
