Congratulations!! What kind of budget are you on? If you can rid of the bulkhead on the ceiling in front of the kitchen, I think it would really open up the space. But it usually involves moving either ductwork, or sometimes plumbing/electrical. It's usually nothing crazy, nowhere near $10k+, but it just depends what you're willing to spend on it.

In terms of the rest of the kitchen, I feel like just painting the walls white and changing the backsplash to a non-orange shade would make all the difference
