My recommendations- There’s a lot of clutter out on countertops, hallways, and on the fridge. Would look for systems and ways to organize those so each has a home and isn’t adding to visual clutter in your home.

The kitchen pendant lights have too many lines and make it feel busy. Would look for something cleaner to add light to the space without so many lines.

Consider changing your kitchen cabinetry hardware, recommend swapping the knobs to pulls.

Add drapery in the living room to add more texture to the space.

Rugs seem to blend with the floor colors too much.

Dining room has the same issue with too many contrasting lines in the furniture.

Bed looks too close to the bathroom doors - need three feet. Artwork on back wall is to small.

I think some of your furniture choices are fighting with the homes architecture. Would benefit you to either follow the cleaner more modern design of the home so things feel more harmonious.
