I love the framed pictures at the end of the wall, but this is just my own petty little opinion, I think it would call less attention to the backsplash dilemma if the pictures were centered on the wall space between the door and cabinet shelves end. That way you would never even think about the backsplash and just look at the pictures and not wonder why they weren't centered on the wall, which in turn would lead to explaining the dilemma about the splash. I know that was a run-on sentence...sorry!!!

I would bring it down from the end up your upper cabinet. On the one side right by the door you "could" take it all the way to the door frame & down to the floor. But to keep it uniform to the other side I would probably end it at the upper cabinet as well. Otherwise you will have it sticking out the top & you will have to have a bullnose piece & decide how to do the corner.

I agree with Errant. I almost always prefer the tile to die there than carry around the side wall. I've been living with painted backsplash area for almost 3 years and haven't needed a touch up in paint except maybe where the raging flame from my CC rangetop has discolored the are directly behind the center rear burner from my extremely high heat searing and stir frying.

Assuming the right side of the upper right hand cabinet is an inch or two from the corner, I'd stop the splash there. I don't like the idea of running it all the way to the corner, because I think it would look awkward from the side. I'd cap the end with metal (Schluter), but any unobtrusive cap would be OK. Honestly, I'm more concerned about the way the hood isolates the upper right wall cabinet - it looks lost over there - and would think about continuing the tile up to the bottom of the hood, or even up to the top of the wall cabinets, to tie it into the rest of the cabinet line.
