This looks very nice- I like really like the airy light.
One thing that pops out to me is that though the modeling style appears to be intended to look as realistic as possible the image feels like it’s on a dollhouse scale.
I think this is caused mainly by the size and extreme reflectivity of the floor tiles. In the scale of the image the floor tiles are much larger than the usual max of approximately ten inches- perhaps twice that much. Additionally the grout lines between them is far larger than it would appear in a real floor and most floor tiles are not that reflective or specular. Wall tiles in a kitchen or bathroom might be, but floor tiles are not.
If you are trying for full realism, I suggest you tinker with the floor a bit and you might be amazed how much more realistic the suddenly becomes. Another even easier trick to give it a hint of realism would be to add a strip of floor molding along the edge where the floor meets the dining room wall.
