Hi,
IMO you have too much occlusion on those spots
if you're adding the ao pass in post, maybe you could soften these parts a little.
Also we can see straight through the rooms on the right, maybe you should add something to break that. Like a chair, corner of a coffee table...
Also your camera target isn't at the same height as the camera so the vertical perspectives are a little distorded, you can click on "guess vertical" in the cam settings. It's not adding more realism but just an option. We're using it a lot on outside views, don't know if it's used in inside views ?? Maybe someone could enlight me about that ?
Great rendering anyway !
edit : I just saw this, it's a good thing you lowered the light on the far right, it's preventing the eye to escape from the principal subject...
