Hello :)
Bed in the corner is fine if it's just one person.
There are a few different schools of thought for Feng Shui. According to the one I've studied, your desk would be better at the bottom middle of the pic, next to the door. This is the "career" section of the Feng Shui octagon of your room. It all depends on the "Mouth of Chi", which is where the door opens. And if you move it there, the door does not open to your back. Where your desk is now, can lead to feeling unsettled while working, because you can't see who is coming at you from behind.
If you can swap it with the bookshelf there, and have the 2 bookshelves next to each other, this would be better.
If you can't swap them, then you can place something on that bookshelf (the one at the bottom middle of your picture) to help balance the energy of your career. Namely, something black, midnight blue, or anything that represents the Water element.
The door does open the wrong way, but people who construct houses often do things wrong. To compensate, you can hang another mirror on the wall there, between the window and the door, or move your current mirror there. This will allow you to see who is coming through before the door fully opens, and allow the chi to flow in better.
Your mirror is currently in the "children" area of your room's Feng Shui octagon, and unless you have children, you don't need to energetically expand that space, so the mirror can be moved to where I mentioned above. This will also energetically expand your Knowledge/Self-Development area, which is something many Zevists are interested in :)
