Thanks for your suggestions.
Agree on the lighting in bedroom. I plan to buy two table lambs to improve it. I like the color of my wall though - it's painted not wallpaper, and don't you think light dirt color would be too blending in with my bedroom furniture? I'd like some contrast.
I do not like the sofa in my living room either. It looks too big here at my home even though it looked much smaller in the store. It's a final sale so I cannot return it. I guess I will just have to learn to get use to it ;-(
