Hi, your home looks pretty good, you have done a lot on the interiors. Coming back to the question, yes, you can add a wallpaper behind the television, go for a textured wallpaper as it will create a compliment to your television. As you have decorated with wooden elements, you can go with a bookshelf on the wall. And, there is one more thing which will be a simple addition but will look perfect and that is an antique wall clock. An antique wall clock will make your wall look great without any fuss.

Beautiful bath. If you love the taps and shower head then go for it. Again, it is your house and you have to look at them everyday so pick something you love and don't worry about anyone else :)

I also think matte black handles will work well. They are simple and elegant and won't reflect light as the S/S ones do. If and when you add a pendant light (down the track), I think your focus on the handles will diminish. It's possible a suspended ceiling will complicate the look of your kitchen. What is the height of your ceilings? And a suspended ceiling would lower the height to what? Painting the ceiling sounds like an alternative and would certainly add interest. Your kitchen IS beautiful as is. Pls keep us posted!

Oh, forgot to add...........If you painted / wallpapered then put clear glass on top, if adhered/glued, there is no guarantee the glass will come off in one piece. However I have a friend who wallpapered, then put clear glass that was fixed on the corners with bolts (can't think of the word), so that it was removable. You can probably get a tiled look paper. Each to their own. I'd stick with a painted glass splashback.
