It’s a good effort, congrats on living in what appears to be a pretty cool place!
Overall I think the walls and ceiling are a bit too uniform. Even if they had just been painted, there would be some slight imperfections that would show.
The specular highlights on the floor seem a bit too aggressive, once again even if the floor was brand new and just waxed, it wouldn’t be quite so “oily” looking.
Lastly, it doesn’t seem to have a “lived in” feel. Even if your own room is that neat, you might consider putting a couple of frames or posters on the wall, some trinkets on the dresser, perhaps a pair of shoes on the floor.
For your own sake – don’t stash what looks like an 88-note weighed keyboard controller on what also looks to be an Ikea wall shelf. That thing will give out in the middle of the night and kill you in your sleep!
Good thing you have a reference take a picture with your phone camera from similar angle and compare the results. And you’ll have a pretty good idea what you need to do to improve it.
So far, it’s a good start.
