These pics get better and better. Fantastic room.
You did such a good job of coordinating everything else on the kitchen side of this room into a seamlessly calm sea of beautiful white cabinets and marble that the blue tile feels like the odd guy out. Yes the blue matches the seating of the room but kind of sticks out like a sore thumb where it is. Live with it for a while and if you still don't like it, do a half marble splash behind the range. Mine was super easy to put up, the counter dudes installed it the same way they did the short splash.
