It looks great to me.
What was composited? Just the wall? or the floor too?
Nice color match/white balance match.
The perspective of the wall looks a little weird, like it's leaning backwards. It looks kind of like you are shootng down at a carpet, at a non-perpendicular angle. (maybe because I'm leaning back in my chair)
A subdued baseboard to straighten the line between the floor to the wall might be nice and add some more detail.
