I would move both of your pothos. I’d slide the one over the oven closer to the corner and find a way to allow the vines (limbs?) of it to ‘climb’ along the wall above your sink. I would also consider a way to have the other ‘side’ of it branch out between the rafters. (Maybe not screws for the rafters, but perhaps something fun like vintage clamps?) Same for the other pothos, move it over so more of the green is exposed on the wall above that bigger window.
Pick up a small bit of stained glass art and stick it in the window, too.
Mess up the design aesthetic some - Get an earth-tone placemat and a craft-y looking bowl and fill it with fruit or if you’re not a fruit person, something pretty and useful enough that it won’t get dust covered. (Grab and go snacks in bright packages?)
I’d reconsider the lights above the cooktop. Maybe find ones that are a bit more decorative, or certainly ones that aren’t just black.
Put a cork board or a chalk board over the cabinet to the left of the oven, and keep colored post-its or chalk handy.
Maybe replace the handles on your cabinets with something brightly colored or with a bit more character/individual craftsmanship.

I guess the idea behind most of what I’m suggesting is to make it look lived in, and to give it some warm tones/break up the stark whiteness of it. The individual suggestions probably aren’t as important as the overall idea.
