1st thing is get new console for TV.

Can you move chair and ottoman closer to the arm of sofa? SO it is facing the tv more?

The console is too small for the TV, you need something bigger. I would try and find somewhere else for the desk and put the recliner and ottoman there. For colors look to your trio of pictures they have beautiful colors in them. Pick either the green or gold to use most and then use red sparingly for a pop of color. Try using the chest beside the couch as an end table and don't worry about a coffee table.

I would move the sofa to the big wall, and put the chair and ottoman under the window. This way all seating has a view of the TV. Definitely a larger TV stand. Use the turquoise piece as an end table. By moving the couch you can also anchor your triptych of pictures over it. I Know this means the desk has no corner. Can it go somewhere else?
