Overall, pretty nice.
However, the marble needs to be a lot more shiny. Both counter and wall behind the stove.
I would put curtains, blinds or shutters on the windows.
L I am's suggestion of some kind of foreground and turning on depth of field is a good one. I would set the focal point on the sink or stove. Or.. whatever you are trying to "sell" in this picture. Maybe the dog bed. Also, a table would be perfect, but you only need to see just a small corner of it so it does not hide the dog and dog bed.
The wood needs to be a bit more shiny as well as the floor.
L I am is one of the best render people here. Whatever he suggests is usually spot on.
Again, it's overall very nice and a client would be pleased, but try the suggestions and it will really shine!
