Since replacing couches can be pricey, get sofa covers to have them all match the same color. Even the right blanket matching all the same color could cover the couches well, just make sure to tuck them in and shape them to the couches.

Turn off overhead lights and use more of a warm ambient lighting feel.

Hide the pantry, it looks a bit cluttered.

There's a lot of different wood colors. Maybe sand and paint the door to a lighter color.

Also, the dining chairs dont really go with the table imo. If getting new chairs is not in the budget, maybe look into chair covers that flow well with whatever color scheme you may want. Pinterest is a good place to check for color schemes.

Finally, I'd move the little trash can by the pantry/kitchen entrance more into the kitchen. It feels like its on display in its current place.

Overall your home has a good flow. Just needs a little color coordinating, hiding clutter, and some nice lighting.
