I think I agree with Elsdon as far as why a lot of interior renders look fake. Quite often, all the things that make a room feel used are left out or are too “staged”. Here, though, while this looks like it could be a staged piece, there’s enough in it to make it believable as a place someone lived in, especially with the wrinkles in the pillows. I think some on the bedspread might could enhance this a little, or even a "turned down"so that the bed appeared only partially made. But perhaps the person here is a little neater and has made the bed Maybe just some subtle wrinkles (not too fine, because of the bedspread, but not too high to keep the “neat” look and feel) could help that here.
The one thing that really feels off to me is that the ceiling feels too high compared to the bed. It feels to me almost as if the room has a “vaulted” ceiling, rather than a more “standard” ceiling, but perhaps that was the effect you were going for.
Overall, though, I really like how this one was done, and I think you’ve done a fantastic job in capturing the scene.
