Hi, for me there are 3 issues.
The toilet needs a basin,
The WIL is a waste of space. Line the hallway both sides with cupboards for the same storage and give the space saved to achieve a basin in toilet and get shower door away from doorway. I’m in love with Hiro sliding doors at the moment fro Regency, have used them to conceal my laundry. Full height doors (2700) with tracks flush in floor or raised.

In bedrooms make the robes bigger, keep where they are. Consider the window size, I can’t tell sill height. The windows should be at least bed height above floor and don’t need to be as wide, but that is an external aesthetic as well.
