Help/critique on room layouts

We’re moving into a new home soon and we were trying to figure out a good layout for our main rooms. I used the IKEA room planner to visualize the rooms so specifics furniture and colors are not accurate. I used mirrors as placeholders for where a tv would be.

The master bedrooms seems pretty empty. We’re planning to mount a tv to the opposite wall from the bed.

The living room has a fireplace that protrudes under the tv so that is represented by the brown rectangle.

The game room I would like to have dual purpose to be able to have board game nights, which is why there are two pictures. First picture is with a fold out table for game nights. Second picture would just be a normal layout.

The dining room has a built in buffer counter that also represented by the brown rectangle.

Guest bedroom has a closet that protrudes into the bedroom, which is represented by the white rectangle.
