I can see you like minimal furniture and clean lines so I will remember this when I comment. You are getting a new bigger tv, which I think would help balance the wall/tv ratio which is great, would you consider a long, low entertainment unit? Regardless that your tv is mounted. Have a look at this website; www.sydneyside.net.au Also, I do like the dark rug (recently bought a dark charcoal one myself) but it looks too small for the space. The next size would have worked better. Sizing is everything with rugs.

When you render the bricks I would consider leaving some of them exposed here and there - that reminds me of old Tuscan buildings! I would include some large terracotta pots with olive trees or lemon trees, also as others have suggested some brightly coloured geraniums in hanging baskets against the wall or in terra cotta pots. Here are a couple of shots of my back deck (which isn't looking its absolute best) but to give you an idea of the large pots and colour. You have a beautiful spot to work with good luck! Sue

How about a water feature? Inspiration.

The mirrored wall certainly gives you a 'wow' factor and the floor is stunning. I wouldn't do a textured wall paper or metallic, I think you'd end up with too much going on in a small space. If anything I would perhaps paint the white wall in a very light grey to pick up the grout in the floor tiles.
