Here is one idea - pretty standard hedge plant.

On the top level you could grow both edible ginger and turmeric. Growing these plants will allow you to enjoy their flavours in your food from your own garden. They would also give you a background level for the whole garden. Some of the cherry tomatoes would also give you a ground cover and plenty of fruit on another tier. Checkout the lovely grevillea ground covers on the net. The bottom tier would be soft with some of the grevilleas available.

I love the idea of using a mix Jadownes! It's funny, before starting work for this company I probably would never have considered using artificial plants for anything... I think for me I always had the mentality that fake plants didn't look very good or weren't capable of looking very good. But now.. I love the artificial plants! Of course though, If I had the time, space and ability to use real plants for my vertical garden I would in a heart beat! I think they look good regardless of which way you go and they offer a unique solution to creating some breathe taking spaces!

Just thinking, have you tried tv on a/c wall and small couch , lamp in front of large windows, love that rug from Freedom would tie in your style, some beautiful textured cushions (love the ones you have) maybe even a Mongolian one to complete the look and a tray with some special pieces would look wonderful, I love boho luxe.
