I would put the bed on the wall in the last picture I think . A fllor plan is always a good idea to scale with destails like doors windows closets etc.

Congrats on your new home! I like to walk in and see the headboard, so I'd put the bed between the two windows. Even if it overlaps them some (see below). Then a low wide dresser on the opposite wall with the TV on it. The current dresser is far too narrow for that size tv.

Bed between the windows, TV above the media cabinet, a rug wider than the bed slipped under the bottom 1/3 of it. All of your art is too small. When you hang art it should center 5' above the floor or 5" above furniture. If this is a 7.5' high ceiling, make adjustments.
