It's refreshing to see nautical, navy BLUE. Everyone is saying the same thing for the most part - just introduce another color, definitely bright (yellow or orange IMO) and it will make it more current. What I really like is how your style will withstand the test of time - and with minor updates now and then it will always look fresh and "current".

congrats! first, sand prime and paint out those cabinets....i'd go with a grayish shade of white or pale gray that will work with the flooring. i'd also carefuly chip off the yellow tiles. since on a budget, consider applying some beadboard as your backsplash, painted in a glossy, oil based or marine paint in a crisp white to keep it scrubbable, then, dress up the edges with some small mouldings, painted in the same white paint. this is going to be SO MUCH less costly than tile! and it will look great with the butcher block countertop. you can probably refresh the butcher block with a light sand and oiling. you could even get an additional piece of butcher block (ikea) and create a step-up 'bar' for some stools on the peninsula for some casual seating. then get a pair of pendant lights to hang from the pot lights above (they make lights that insert directly into the pot light...no hardwire necessary).

I read an interesting comment somewhere, where a lady invited a group of her friends over to lovingly point out all the problems they saw (through fresh eyes) with her home on preparation for sale. She said she was surprised at marks and damage that she had lived with for so long she no longer noticed them. We "owner built" a home previously, and when we came to sell 7 years later, we painted the garage and did those jobs that we had put off, and it became sad to finally see her at her best, at the end, when we could have been living in a completely finished home all that time. I read about a lady who decluttered her home, had it professionally cleaned (build clean, or bond clean) and had a professional styler do her home and she realised just how nice it could be and decided not to sell. :) ta

Your client putting trust in you was the right decision! amazing transformations! Love the natural light in particular as thats a great spot for a post gym pump flex for a good selfie!
