In the second photo, I think you end the backsplash before you get to the appliance garage, so nothing on that painted wall. The first one is trickier -- there's no right answer, just your preference between ending with the cabinets or ending with the counter. In your case it's a bit trickier because the counter continues so much farther and even around a bend. I think I would end on the first wall, at a height that is a bit above the bottom of the cabinet. But it's hard to say without seeing the whole wall.

For the first picture I would end the backsplash around the corner with the countertop. I think that will keep it from looking unfinished. And for the second picture, that's up to your discretion. It's such a small amount of wall space that it would look fine with or without a backsplash.

Would you angle the tile to the end of the countertop. I like the idea of not putting on around.

I would recommend stopping it at the end of the counter. If you end it before the corner it will look unfinished.
