You still need some shade. Right now, room is full on ambient light and I think that shadow behind bed and nightstand are impossible, considering the position and height of window.
A bit of extreme example here:

But it shows how light bounces around and how corners and wall that has the window should be darkest.
on a side note, I fiddled with camera for 20 minutes, but never managed to get as steep perspective you have. When floor lines up, ceiling just doesn't. So I think ceiling lines should have much, much lower (more horizontal) angle. On your image it almost feels like ceiling is ambushing and about to attack anyone who lies onto bed.
