With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

Its nice , love it , i am sure there is a cost involved in the making. Its elegant and simple , love it

As others have said, it depends on the space. As a child I loved velvet flocked because it was so "touchable" LOL! In my extended family we tend to use the velvet flocked in dining rooms, the foil in bathrooms, and a high quality wallpaper in other rooms. The design is totally reliant upon the space it is being used in. In our Victorian farmhouse most of the rooms have the big roses or hydrangeas appropriate to the period. The dining room has a gold foil with red velvet (see below). Photo taken by my cousin.

We need a lot more info like floor plans , exterior renderings .
