Living space doesn’t feel cozy

Just as the title says, my space needs some help. I’m open to changing everything except for the couch (it’s the comfiest piece of furniture I own and don’t want to part ways). My kitchen is also getting new cabinets and a proper island at some point in the new year and was also considering changing up the white color.

The space doesn’t get a lot of natural light and I desperately want it to feel tranquil when I get home from work. Maybe I need different lighting and calmer colors because the couch is so loud? Any and all comments are appreciated. Thank you
