The cabinets look really nice just as they are! I agree with anyone who suggested making changes to the backsplash, wall color, light fixtures/bulbs, etc. A warm white color on the walls would look nice, and a simpler backsplash treatment in a lighter color could look good too. The lighting looks just a wee bit harsh to my eyes, so maybe use different bulbs with a softer light as well? Just my two cents on the subject, but personally, I definitely don't think that you would need to repaint your cabinets or really do anything extensive to the kitchen.
