The top and bottom lines of the poster and mirror shouldn't be parallel with the line between the ceiling and right wall. Ditto with the door and closet.
You have to make all lines go towards the vanishing point, which means that no two lines should be parallel unless they are on the same level.
I've edited the left wall in the image above. I've left some of the construction lines in. As you can see the top of the door and closet is slightly not parallel to the wall, because it goes to the vanishing (which disappointingly lies off the edge of the picture).
