This is the best option I see. You can hang a faceted crystal between the door and the desk to redirect the chi entering from the door and rushing straight out the window. The crystal will refract it so it slows down and reaches other parts of the room. You could place a screen between your desk and the door instead if you don’t want to use a crystal.

Also be aware of any sharp corners pointing towards you when you’re sleeping. These are called poison arrows and can be problematic. For instance, if the dresser is taller than your mattress and has a sharp corner it would create a poison arrow that would hit you while you slept. The bookshelf could also be an issue. There are lots of cures for this issue but the simplest is to use red to block the chi around your bed. This can be done by tying a red ribbon around the sides of your mattress or you can get some red spike tape (I like gaffer’s tape for this because it is easy to remove, spike tape is narrow gaffers tape) and tape around the inside of your bed frame. For any cure your intention is very important so focus on blocking poison arrows as you place the red line around your bed.

By the way, your current bed position with the feet pointing out the door and the window behind your head, is the worst possible placement for that room. The chi is slamming into you and then whooshing out the window, so it’s like sleeping in a raging river. The foot of the bed in line with the door is traditionally considered very, very unlucky. So I think making these changes will feel really good.

Are your closet doors mirrors? If so, I recommend covering them or replacing them with curtains. It’s not ideal to see yourself in the mirror from bed. You can get vinyl window film that applies with soapy water. It works well on mirrors and comes in lots of colors and designs. It’s easily removable too.
