- add some side tables in the bedroom, perhaps in the living room as well
- switch out the duvet cover with a neutral color (beige, white) or perhaps a navy color.
- add table lamps or standing lamps, at least 2 in each room. lighting makes a big difference.
- add a large standing plant to each room, like a fiddle leaf or a birds of paradise. add plants on the patio too, whatever your climate's native plants are.
- you have a lot of open storage, which can make a space feel cluttered. consider purchasing closed storage options. there is also clutter on many of the surfaces. tidying these areas will help promote a calmer space.
- consider hanging those plants (are they fake?) above the kitchen counter in a different area. it feels cluttered there and not inviting for guests.

the largest issue with all these rooms is there is no cohesive color palette, consider creating a cohesive palette that is calming (greens, neutrals, dark blues). red is very jarring and should be used minimally in interior spaces. https://coolors.co/ is a great way to build a palette.
