One tiny bit, you could still rotate all the walls on the upper floor as well as the bay window counterclockwise, then there would be even more space in the dressing room. You could possibly also move the staircase a bit to the left or make it narrower and longer instead. That would also create more space in the bedroom (possibly a second wardrobe wall on the left) and reduce the area of the hallway. But that would create new problems and actually I think the plan is great. Only the angled bay window doesn't appeal to me (especially since it faces towards the garage).
