Here are my improvement suggestions:
Ground floor:
Paint the storage room and place a proper coat rack. You do have a basement.
Draw the sofa furniture more realistically; those are dollhouse furniture. I would place the sofa on the other side (interior wall) so it doesn’t all look lined up along the exterior wall. Shift the window a bit to make room for the TV.
Significantly enlarge the window by the dining table.
Upper floor:
Paint the mini utility room and add that space to the bathroom; it is FAR too tight.
Better to put the washing machine/dryer in the attic.
Attic:
I would swap the space for the bed and the dressing room. If not, at least adjust the window in the dressing room so that a wardrobe fits against the exterior wall. You can see on the right half that it doesn’t fit.
Enlarge the bathroom towards the home office; the home office doesn’t need that much space, but the bathroom is too cramped.
The niche with the closet (by the stairs) wastes space. The small utility room could also go there, then you can iron and dry clothes on a drying rack in the dressing room. I don’t see space for that on the upper floor.
