Something like this may work. Note the changed door positions so that anyone in the bedrooms can visit the bathroom without disturbing anyone else in the lounge !

I agree with eztia - you need to give a raison d'etre to your room and pale gold from the upholstery will tie in with the room and contrast against the candy pink wall. If you could find a discreet candy pink and pale gold curtain you would have hit the jackpot!

I think the yellow and grey might bring out the gold-ish-ness of the couch.. I'd try to go with more blue colors.. Maybe some navy pillows and a rug with the blue in it as well. The curtains, that ying-yang rug, and the lilac rug just gotta go.. They're dwarfing all the sophistication this room will be able to have with that tile floor and those big beautiful windows. I love the dining room chairs!

You've got a great space here, and there's so much you can do with it! Do you know what style you're looking to achieve? If you've already got a red and white colour scheme going in your kitchen, you can always opt for this in the living room. Sometimes grey can make the room look a little dark, so it's always worth investing in a white base, and build from there. Maybe change the colour of the curtains to something a little lighter and richer?
