Homeowners Opinions Plz

Mr. Oats originally had the kitchen walls and cabinets painted the ugliest cobalt blue I've ever laid my eyes on (blue is his favorite so )

Decided to redo the cabinets in a dark grey and painstakingly add a stone backsplash to the entire kitchen

Progress pics (and no, I don't keep a tidy workspace so )

Results:

I was feeling after finishing the project, but now Mr. Oats is looking at selling the place so I won't be enjoying my labors for as long as I would have liked to

!homeowners I have redone the kitchen, the study floors, and the fireplace (Mr. Oats installed hardwood flooring in the living room area and granite tile flooring in the kitchen/surrounding hallways) since the place was purchased. Does anyone have a clue how to get the most monetary value on renovations (I want to get ahead of low-balling appraisers )
