In the upstairs hallway, those "weird" corners would bother me, the ones by the bedroom door and the stairs. Just quickly sketched, but I would find it more sensible like this:

I would have tried to design the entrance to the bedroom at a 45-degree angle. Then you can also turn left directly into the walk-in closet. Additionally, I would install a door from the bedroom to the bathroom. That way, if you need to use the toilet at night, you have a shorter way. Isn't a urinal planned in the downstairs toilet? There is space, and I actually find it quite practical. Especially when you have many friends visiting, the WC stays cleaner afterwards.
But that's just my opinion... of course, you have to decide what suits you.
