this looks really beautiful.
the biggest thing for me are the flowers on the table. How did you make them? They look photoshop - esque. I think its because petals have a degree of translucency that I don't think is represented here. They are in one of the brightest spots in the room, the light should shine through them, giving them some more luminesence. and their shadows should be colored.
Also, I think the light on the floor needs a little bit of fuzz around the edges. It is the sharpest element, even next to the modern countertop!
I love the cabinets. Really beautiful image. Good job!
