The first two are awesome! The third one needs some work.
There’s something “off” with your curtains. They don’t have enough detail. And the TV and speakers look too game-like for me. In fact, something is off with the lighting of that scene entirely.
The TV doesn’t have a border. It’s just a black plane in the wall? I think the entertainment unit needs to be a different colour. It seems to be fighting with the white colour of the wall behind it. The floor, shelving and bricks all look very nice.
