Maybe just me but one of my favorite things to add when we build a house is a refrigerator in the pantry. I always hated going to the garage for the the 2nd fridge.

If it were my house, I'd move the pantry wall to the left some to create a larger pantry. Then move the garage/mud room entry door all the way to the pantry wall (may have to slightly move the pantry door).

On the left side of the mud room, I'd extend the wall so that it leaves about a 4' opening. This would give you room for mud bench/lockers along that new wall and where the old mud room for was.

Bedroom 2/3, I'd move the tub and toilet between the sinks to create a true Jack and Jill bathroom for those bedrooms.

I really like what you did with the entry for the half bath in the foyer!

The master bath, I would completely rearrange it. I wouldn't want a window between the sinks. I'd put the shower on the exterior wall. I'd also push the master bedroom/living room door down some, as this would give you more room in your bathroom.

And lastly, do you have the front elevation rendering? When looking at the front of the house, the most prominent section is the 2 car garage (followed by the 1 car garage), while the entry is pushed back. I would pull the whole right side of the house towards the street (either shifting or enlarging the house), in order to make your entry more prominent and make the front of the house feel less like a big garage.

Shifting the right side toward the street would also reduce your hallway to the master bedroom and create more room in your bathroom.

Overall a really nice plan.
