Hello,
even if I feel like one of the few friends of cubist architecture here in the forum, I have to agree with the slender gray creature with the long trunk (11ant) ... somehow your design has too many corners and then there is this forced rounding only on the ground floor. You can see that such roundings definitely fit Bauhaus architecture, for example at the Weißenhof Estate in Stuttgart, but there it is applied more consistently (House Scharoun). In your case, it looks like the architect’s desperate attempt to forcibly distinguish himself at first glance from the prefab house builder.
As an attachment, I have two quick sketches that hardly change the house overall, make the lines towards the street somewhat calmer and, despite a bit more area, probably reduce construction costs.

You could also move the door to the garage from the hallway under a canopy. Advantages are space for a wardrobe, no "break-in problem" from the garage into the house, no visually ugly outer door from the garage into the hallway. And hey, your architect can round off the canopy.
The study would become a bit larger, just like child 2’s room, whereby the wall to the south could be set back a bit to avoid that strange corner at the chimney.
These are things I would change. Partly from experience, partly from taste. But overall, I like your house!
