I would switch the two dressers so the longer one is under the TV which you should lower some. Dress the two windows alike; completely cover them with lined drapes matched to the wall color and hung ceiling to floor. The windows don't look like they provide you with much light anyway and really need to be hidden. Then stand your floor mirror in the other corner. Move the slipper chair in the corner by the floor lamp. Remove the bench/luggage rack to another room.

Does the PB sofa creep into the hall? It does feel a little bulky for that room and you cannot get around it on the window side/no place for an end table. No need to sell. Opt1) Keep the 2 chairs,. Put them side by side as they are with a narrow table between. They are fine. OPt 2) Move one of the sofas in from the living room (appears to be a smaller size than the PB one) Move the 2 C&B chairs into the living room. They actually fit better style-wise with the living room chairs (than the blue ones). Do you need all of those chairs in the living room? Could the blue chairs go elsewhere? In other words, what combination of the living room/keeping room furniture works best?

Most trends that I see are towards whatever the most "open" layout and flows are.

I agree with Patricia that adding window/s to the master bedroom is a great idea--it's always a must for me to have cross ventilation and light in any room, especially a bedroom. But I'm not a fan of adding it as per your plan, with the bed not centered on the wall. Either add two windows, one on either side of the bed, or add a large one in the center of the wall and place the bed between the windows on the other wall. You also need to consider how that will impact the exterior, so discuss this with your architect or builder. The kitchen is not an optimal use of space, which Mark has commented on, due to the cramped space with the angled sink and tiny island. From your rendering it seems very small compared to the giant living area.
