Paint the green wall the same color as the rest of the room. Your TV placement seems much too high, especially for a low sitting MCM type of sofa. I would mount it at eye level either on the green wall or the opposite wall where your Klimt is hung. Then you may want to potentially move your sofa 90 degrees to accommodate. You can also put the TV on an arm that will pull out and angle it somewhat. Wherever you mount it, place some kind of media console or ledge in similar color and style to your coffee table. Potentially relocate the round mirror to above the fireplace.

If you hate this idea and don't want to position your TV at a better height, then still paint the green wall the same color as the rest of your room and get an MCM buffet in place of the furniture you currently have there. I'd get one that is completely closed - excellent storage by a doorway for shoes, hats, scarves, bags, sunglasses. Get something that compliments your coffee table.

No matter what I'd lower the Klimt.

Yep, I'd swap the TV and the Klimt. Reorient the sofa to the new TV wall.

Agree with the above, tv spot is wrong and walls should be all the same color

I thnk the sofa back needs to float and create a room divide, from the entry also allowing to look out the windows, the fireplace, and move the tv between the blanket rack and the tree. reuse the table from the entry as your tv stand. Put the art over the fireplace or possibly the mirror. The art might look better on the green wall.

The cabinet used to be the old tv stand, but was moved to accomodate the fireplace. The fireplace is built in, so not moveable. 

The sofa is too large to move to seperate the room, unfortunately, and moving it to the back wall where the blanket ladder is would completely block off the dining area.

Any further suggestions with that info?

Seems the sofa is too large to turn it toward the blanket ladder wall. A smaller sectional with a chair would have been more flexible. When you can I'd reorient by moving the TV.

just a thought but take one section out of the sofa so it is a better sized.

If you leave the sofa where it is and put it on the mirror wall, will you be able to see it from the sofa? If so, you'd get to keep the sofa in place, put mirror above the fireplace, lower Gustav, and just paint the accent wall.

I was going to suggest the same as Kendrah. However, I like your accent wall color! I just think it’s on the wrong wall. I’d paint the fireplace wall green instead.

I've moved the sectional just a bit away from the window wall to give the room some breathing space. I would find a better, larger canvas for the back wall and add a floor lamp to the room.

Be more deliberate in selecting items and placing them. The biggest issue in the room is that accessory placement is a bit too random IMO.

Bringing the color of the sectional over to act as the background for your fireplace might help this wall "float" a bit less.

If sofa can’t be reconfigured, then let’s tweak…remove the ladder, pull the sectional away from the window so the back of it aligns with vertical plane of the window cornice. Center the Klimt 6” above the sectional on that end wall. Place the tree to the right of the sectional but centered in the space between the sectional and the wall. Cat toys could go behind sectional. A fabric storage basket next to the tree could hold the extra throws. Move the framed baby footprints to the baby’s room. Move the plant that’s to the left of the fireplace to the right side and move the bromeliad plant to the left of the fireplace. Keep the two hex shelves in the same positions, relative to each other, but move them down so that the top of the green portion of the left most shelf aligns with the frame at the bottom of the tv. Paint the entry wall the same color as the rest of the room. Move the bird cage onto the cabinet with a couple hardback books placed underneath it and the coffee table plant placed inside it, if possible, with the other plant grouped with them. Group the other 3 items on the right side of the console cabinet. Then move the plant on the bottom shelf to the coffee table. A basket of baby gear or toys could go on the bottom shelf of the cabinet. Fill all 3 cubbies with storage baskets.

I wouldnt do much honestly, maybe just do a decorative wall and remove clutter
