You uploaded your pictures sideways. This could be my home. Ranches, I find are usually so boxy. You have to work really hard to make each area stand out and compliment the other rooms. Try bringing in a color from your family or great room. Add some nice flush mount or pendant lights. A more colorful rug and maybe , it's hard to really see just how much wall space you actually have but some reflective or different frames on the wall

Paint one wall a bright happy color and add coordinating. I like Ralph Lauren Claude, as it's yellow without being YELLOW. I had done as tone on tone stripes in my living room.

Stenciling that long wall might be nice too and add visual interest
