Thank you. if i change dining chair cover and wall color to traditional sofa color( gray+green). Also add more victorian decor, cofee table set would be round leather ottoman (dark brown ) would traditional sofa work?

The white ones would look perfect with what you already have, the green ones wouldn't work at all. You could perhaps do that kind of victorian-ish furniture, but it would have to be styled just perfectly. For example if the wood was done in white or a bright color, and the upholstery would need to be something more modern and I think something with a graphic print. Unless you are planning to replace your wall cabinet and dining set, I'd stay away from the green sofa.

wow, it was big help. Thank you so much.
