A fun and happy piece of art above the table would liven the place up. I think the scones are too small. Consider new lighting.

Nothing above the cabinets. I agree a piece of art, or a collage of art would be great on that wall... not sure what purpose the sconces serve. New chair pads can be purchased at so many home stores... Bed Bath & Beyond comes to mind... save up those 20% coupons.

Or, maybe a bit of something above the cabinets! Depends on how many cabinets you have & how much other stuff you have displayed in adjacent areas. If you do add anything, try larger items related to some theme - no small dust catchers. And maybe it’s something that ties into green of chairs. I have really large decorative platters on easels & some bigger ceramic pots above my cabinets. Easy to get the platters down when needed. A suggestion here - you made an investment updating backsplash & counter but what about your cabinet hardware? I think you’d get major impact updating that item! You’re changing your stove & hood to stainless & black which will be great with your BS tile. Depending on what your other appliances are, maybe consider polished nickel handles? Mixed metals work in kitchens too. I agree about the sconces - I wondered what the rest of that corner looks like and if there’s lighting above the table. From another of your pics it looks like that table is in kitchen.
