I’d say the room looks dark, i’d either increase the exposure or the strength of your lights
Also, usually there’s a thin wooden “frame” between the floor and the wall (i don’t know how it’s called in English, in Italian we call it “battiscopa”)
I’m not sure if the scale of the noise on the carpet may need a reduction, and you already wrote that the rug needs some bumping, it looks like marble right now
Depending on wether it will be noticeable or not (which depends on the distance of the camera from the surface and the part where the floor joins the wall), the bump map may be unsuitable and i think you may need a hair system instead (not sure about this, i’m notacquainted with particle systems yet, as well as many other things :D).
Then, the room feels a bit “big and empty”, but i don’t know how to remedy to this.
Feel free to take my suggestion or not, and if you do, do add a pinch of salt.
