I think they look beautiful. Perhaps try using a marble backsplash. Maybe polished botticino? We used crema marfil in our kitchen but I think it loos more like botticino.
I would also think about using a darker finish for your hardware. Once, you make a few changes you might find you like the color of your walls. They go very nicely with the cabinets.
