Unfortunately all your options require custom work: It looks like you need an 18" corner cabinet. You will have to modify the last wall cabinet on the left. As I am eyeballing it, you should be able to cut the last cabinet in the middle and then shorten the left section to fit the space of the wall next to the door trim. It's an option that makes the area looks symmetric. Or you can install shelves over the sink. I would not recommend it because it will take the looks away. And the last option will be to remove the last cabinet, shorten it so it fits over the sink and install a single cabinet where the double one was. This will leave a triangle space behind the corner where the two cabinets will meet. You can block the space under it. Hope this helps!

I would use the greens from your bedspread. Since you have green in the bedspread, and brown and white tiles, those 3 colors need to be your focal point. So I have painted your wall a bright olive green ( the darker color in your bed spread) and the ceiling either a brown to match the tile or a white to match the rest of your ceiling. then or I think this last one is a little tamer . But you should be able to paint over the tile. WHAT kind of tile is it? If it is ceramic you can paint it.

Instead of the solid grey, you can go for sketches in grey with flashes of mustard/ yellow. Or, look up these links for wallpaper ideas https://goo.gl/images/OrCtY1 https://goo.gl/images/0ZpAmU
