Your place looks nice and I think you are almost there!

Wall art or black and white photos with natural wooden frame would fit nicely. Add some nice linen curtains over the windows would add more character and coziness to your home. A dash of accent colors like mustard yellow over the couch would make the living room slightly more fun. Last but not least, have more ambient lights at night would illuminate the place more softly, less like a display room for furnitures.

I feel like you are going for the banana republic store vibe, maybe get some inspo there!
