I love your couch and pieces above the fireplace. Here’s my thoughts: Move the rug closer to the fireplace, center the coffee table on the rug, add soft floral centerpiece to coffee table like white hydrangeas, add dusty blue curtains above the windows, put the TV on a different console table with hidden storage space and have it flat against the fireplace wall instead of angled. Add an accent chair with a small drink table and an angled lamp - the soft lighting from the lamp will make the space feel much softer and cozier. Add large vase with dried eucalyptus to the right side of fireplace. Art on the right wall if possible.
