I don't know much about lighting, but I'm not a fan of having the wall that pops out (right one) a darker color than the background wall.
I also find the shadow gradient along the wall weird... If you're gonna go with it, I think it should be a much more subtle change.
(And even if you were to want that extreme value change, you should avoid having such obvious banding)
All this advice is invalid if you wanted a heavy light/penumbra contrast (like the unending light reflection on the floor suggests)
I fidgeted with it a little bit- removed the extreme gradients and changed the wall colors to what I think would be more appropriate (though the window wall probably should be darker than that...)

(not sure if I remembered to change the color of the wall between the potted plant's leaves)
I assumed the room was well lit, but if you want an old empty house a la a3um's pixelart, the darker point of the room would be the far right corner, which wouldn't receive direct lighting (only a bit of rebound from the room). The 'middle' corner (which you had most heavily shaded) would also be dark, but not as much as the far right corner.
Also, the shadows that the sofa and statue cast are too short for the suggested angle of the lighting (alternatively, the lighting reflection is too long compared to the shadows of those objects)
Hope I wasn't too confusing
