That already looks significantly better. The children's rooms on the upper floor are okay, the built-in wardrobes are efficient. The beds shown are not 1.40m or the wardrobes are not 2m wide. As already says, the bedroom is too small, as is the wardrobe. The hallway still needs to take up less space, and the bathroom can be a bit smaller as well. The ground floor is probably feasible like this, but I think that too much space is devoted to the 'hall' in front of the stairs. This makes everything open, but at the expense of the kitchen, which is in my opinion too narrow, and the living room could also be a bit bigger. The table looks like a doll's table, so please draw something in a reasonable size here. The direction is right, optimize the traffic areas once more and it will work.
