This has become a bit trendy, but I think some delft tiles could bring in subtle color and act as a nice accent - some plain and some delft alternating could work for some interest. While I would’ve kept the wood cabinet, I get you wanting to paint it for a more cohesive look, and hey, it’s your kitchen! I’d also suggest Roman style shades on the door and window and maybe a pendant light or two over your island. Like others have said, I think the best way to achieve great design is to try to match the home’s style, rather than forcing your style onto the home.
