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.

Sounds like your daughter's already got some interior designer instincts ;) Loving the black feature wall, and you don't want to take anything away from such a strong statement, so I think you should go with white... or at least a very light grey, e.g. Dulux Lexicon quarter (on the left)...

If you are keeping the rug, take the blue or pink out of it, and use that as paint colour. Only problem is I think the rug may be too small. We like to consider each room as a whole, can you post different views please? Leave out things you're not keeping in there.

Depends a little bit on the style of your house , but my first reaction is the same as bigreader -- no , and almost certainly no , no , no , no , not 4 rooms in one house . Some of the schists look alright , the 80's style might suit an 80's or even 50's minimalist American house . There are some fairly cool 'wavy' panels that are available these days ; even some feature walls that look like timber ends sticking out of a wall ; wallpaper works in some places ; but one wall of brighter paint is the most obvious 'feature wall' . Faux Stone , or that ship-lap timber , or diagonal timber are about as exciting as yellowy beige or mission brown .
