Hello!! The coffee table and rug are way too small against the scale of your sofas. Adding a larger rug would certainly be an excellent way to bring in some color. A mirror or artwork opposite the window, will bring balance. The window panels look as if they are stacking on the window itself. Is this correct? Stacking the panels off the window will bring more light in and make your window look larger. I'm assuming they are store bought? If so, add two more panels. Good luck!

I agree. Invest in a larger rug, in shades that complement your curtains. That will anchor your room and inject some colour into it.

The rug should be large enough for the two couches to sit completely on.

Houseplay i was thinking of adding some white shelves above the couch with different picture frames on it? What do you think or should i just add a nice mirror? Also what other colors should i add to the room?
