I quite like you're interiors, especially the living room. The kitchen is a bit too "North American" for my taste (strong and heavy colors and shapes).

Some tips to make your indoor renders look more alive and realistic:
- Add frames to your windows
- Almost every surface can use some specular and some bump (this will naturally increase render time). This is not so important, if you're scene is only lit indirectly (light coming in from the windows), because there's not so much light to reflect. But if your scene is light also artificially with lights inside, then it's important that your materials are slightly reflective and not perfectly smooth - like almost every material in real life - because there's so much more light to reflect.
- Use soft shadows (Scene settings - Lights-tab)
- Use Metropolis Light Transport (preset 19) render method for the final render. PhotonMap - Quick (preset 3) is a quick way to test the settings when setting up the scene.
