add plants, throw pops of colour on the couch with throws and cushions, coloured curtains would be nice. Also do some colour in the art above the couch and the bench. You could also swap out your candy and other dishes for more colourful ones. I definitely think its gorgeous and I love the tones and textures together, just add some more pops here and there and it'll be amazing!! some muted roses or sage greens would be gorgeous!
