wow, drastic improvement. I disagree about needing specks on the floor - maybe add an actual rug for some accent value but I think, especially for this style of iso, you can get away with a smooth floor like that. nobody is going to look at it and be confused about whether or not its carpet!
However, I think you need to show that flatscreen monitor the same love that you put into the other stuff - its lighting seems arbitrary compared to the other elements, and its color ramp is very blah, especially compared to the bed and walls. The screen's bevel looks thicker on the left, and the dark areas don't seem dark enough on it. The diagonals on the screen don't make too much sense either, as LCD screens aren't generally reflective; maybe you could squeeze a little icon or something in there instead? personalize it, instead of just letting it be some weird furniture display prop
