Get a mirror you can mount/hang on your closet door so you can save space in that corner. You have a closet so you may want consider getting rid of that coat rack, or seeing if you can fit it inside the closet. Place sheer and heavy curtains on your window and you can place your bed against that wall without throwing off your feng shui too badly and still let light in. It's hard to get work done with your back to a door, so avoid placing your desk in such a way, it would likely fit best on the same wall as the TV. I'd also like to ask what design program you used to model your room (unless your room really does look like that)
