Upper floor layout planning with sloping roofs - What to improve?

I am certainly no floor plan expert. Nevertheless, I would like to make you a proposal for the upper floor. Sliding door to the master bedroom. Storage space in the hallway for bed linen/towels/vacuum cleaner, larger dressing room, larger office.

Showers below the 2-meter line do not work. You can't just place the windows under the slope like that either. You are ignoring the roof, small knee wall, and roof slope here.

That unfortunately is strikingly true, however: the tub and the bed are positioned in the "Original" just as unfavorably.
