Assuming the windows are on the wall to the left of the door on entry, I would give some thought to flipping the bed through 180 degrees as per revised option B so it faces away from the window. Depending on how much you like lying in bed staring out the window or at the mirror robes. Then the Alex drawer can be put next to the head end and be your bedside table but will still be accessible to the desk. It will help screen your bed from the doorway too. Moving the bed from being jammed up against a wall/window at the head/foot end could make quite a difference to usability. It'll simplify changing sheets quite a lot if you can easily access both head and foot of the bed. Even if the access is only 30 cm or so. Opens up access to the full width of the mirror robe too.

Not much room for a reading chair either way. B is a bit less cluttered, but very much a one person layout. Don’t know if I could sleep facing a mirror.

I reckon option b is the winner too. I nearly did the same except I do a lot of zoom stuff and hate fake backgrounds and hate the idea of people seeing my messy bed! For now I have poked the desk into my living room.

That carpet has seen better days!

Oh, you have done well.
