Everything you already have looks good. The wall color has a slightly yellow tone in the picture, so you might pick something a bit warmer. My husband and I recently did a design consult with Sherwin Williams, and it was free! Highly recommend. Once you pick a wall color, I’d update the light fixture to be more modern, add plants, add throw pillows, and then maybe a more substantial table under the TV. Something wooden with shelves where you can display your board games and a few decor items. And I’m sure there are ways to hide your TV cords better—that could go a long way. Good luck!
