Much better.
I would relocate the entry to your study. Closer to the inside of the house and preferably better access from your master bedroom. Why walk through half of your house to get to it.
Wi-fi central antenna? Internet access to bedrooms, especially if you kids are older; however, even if they are young, they do grow up too fast.
Better access to the house from that 3 car garage besides through the utility room?
Is wife into sewing or quilting? Combine utility and enlarge? That space, I think, between the utility and br4 is wasted; build it in and enlarge the utility or br or split the gained space.
Don't rush into building. Go through your plans in both of your minds how you habits accommodate the traffic patterns and needs.
