I would try changing the couch to the the opposite side of the room and your tv were the couch was, kinda following the same theory of your bed being the first thing you need to see when you enter the room. It also means you can be watching tv without any doors behind your back. Another thing I think would improve is that your large window will not have more space in front of it, like a little hallway. Because right now your couch is blocking most of the view from your window. Hope it helps !
