I would reconsider the arrangement of the bedroom, dressing room, and master bathroom. As it is now, you have to go through the bedroom from the dressing room to the bathroom and vice versa. Meaning: if one wants to sleep in longer, that's pretty inconvenient.
I also don’t have a clear idea right now where north or south is here.
If necessary, I would also consider swapping the children's bathroom and the utility room.
I find the doors in the children's room okay as they are; otherwise, there is enough space for cabinets and shelves. I only find it annoying if there is space behind the door but not enough room for a cabinet or a shelf. That would be wasted space. As it is, it's perfectly fine.
Overall, I would miss storage space. You don’t have a basement, the technical room on the ground floor is not particularly large and loses floor space due to the garage access (is that necessary?). There is also no pantry anymore. Where is all the stuff for a family of four supposed to be stored? I don’t see anything...
