Almost gallery worthy.
I still think the height of the middle level is too low. If you put a 6-foot tall person underneath, there's maybe a foot or two of clearance. That makes for extremely cramped quarters in the sitting area.
Now that I look at it some more, the door on the right/lower level seems a bit small compared to the couches. Either the couches are really big -- 4 ft high -- or the door is really small -- 5-6 ft high. Something needs to be adjusted.
Also, I would adjust the framing of the image to eliminate the black background. That might entail adjusting the camera and/or moving objects around. We should be seeing the room not a part of a box with interior elements.
The lighting looks really nice though.
