I think you laid out you furniture from the perimeter into the middle of the room trying to fill room up. Instead, imagine aa area rug placed in front of your TV. Let's try the sofa sitting just on imaginary rug facing the tv at an angle. Place your chairs on either side with a coffee table. Outside of the rug, create another seating area. From the reflection in the large windows, I see a wall of pictures. You like stuff! Me too. But all your little furniture is overwhelming the space. Try pulling everything out. All the kick knacks too. Introduce it back slowly. It may end up all going back because that's your style. Or you may see the space open up and like it! Either way, Houzz is going to ask you to edit! Gird your loins! Try some of our suggestions and repost your efforts! We'll come back to you. Ps my illustrations are just to show you the rug concept, not furniture placement necessarily.
