First: Late design changes are problematic and can, especially once a staircase is involved, throw the entire design in the trash.
Entrance: mentally remove the wardrobe and storage room. Then add a new wardrobe on the north side of the staircase, preferably deeper than the usual 60/65 cm. Then add a bench and shoe cabinet on the exterior wall between the main and garage entrances. Nice doors to the garage cost money; if there is not enough available, the door can be hidden by appropriate measures.
Bedroom: it must not appear too convoluted.
Other: your planned furniture style is not clear to me. Regarding the exterior of the building, freestanding cabinets or cabinets in niches might fit better than modern built-in wardrobes...
