The furniture is set up like a TV room but there is no TV. The sofas and chair should relate to each other. Flip the couch and love seat and Add a big coffee table in front of the couch. Bring the chair over to an angle by the love seat so that you have a coversation grouping.

Then, art on the walls above the sofa and love seat.

Back off the amount of yellow in the wall color to a warm white like SW Alabaster. Put up teal drapes (the color in the chair and the throw pillows). Even if you never close them, you need some color. The sofa matches the carpet which is not doing the room any favors, but if you like carpet instead of wood floors it is what it is. Auntthelma is right about the furniture arrangement. I would also replace the crystal lamps.

This layout could work for your room.

IMO too many wooden furniture pieces. Move the desk, etagere & console table to other rooms.

What do you use the room for?

Look for wall paint in the greige color of the chair's fabric background color. Get large samplize pieces to try in your room. Make sure the paint complements the rug.

Widen the curtain rod and push the curtain panels to the edge of the windows.

Use blue in your accessories. The yellow is not good with the rug or sofas.
