A bit of glow and you will get rid of those jagged edges on the two light spots. :)
Rest looks nice!
I like the lighting and low contrasts, as well as the reflections on those vases quite much.
Just apply some decent finger prints on those too perfectly shiny pots... and on the vases / glasses. My suggestion.
And... that marble surfaces should look like real marble. Looks like plastic at the moment.
Switch on some SSS / Volume on the material.
Also maybe a bit thinner. In reality, Carrara marble in that thickness would cost you ca. 6000,- EUR.
But maybe your "virtual client" in that scene can afford it. :)
Also put chamfers on the marble edges... it is usually done like this... not radii.
