I am also not good at creating floor plans, but for me, a lot of things don’t fit here either. The reading corner looks narrow and uncomfortable. The many tiny rooms in the middle, mostly intended as parking spaces, but nowhere do any cabinets fit? (Am I seeing it right that the utility room has 4 doors? I'm not sure about the representation. Sliding doors and once through a cabinet?) I don’t understand the walls in the children's room. Why not remove all that stuff and put a cabinet against the wall and space for playing? (Is that thinking too simple?) Does a real wardrobe even fit there at all? If it’s "only" about the parents’ area, then I find it strange that the laundry gets a window, but the dressing room doesn’t. Otherwise, if I interpret the drawing there correctly, the utility room has a passage to the other side, then I would save the passage to the dressing room and would rather take more storage space both in the dressing room and in the utility room... but actually, I don’t like the whole structure at all, so, uhm. Depending on the representation, the shower otherwise seems hard to enter, but whether it actually fits in terms of dimensions, I don’t know....
My overall feeling is also: throw it away, start from scratch.
