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.

You don't necessarily need only paintings as artwork. You can put some floating shelves near the dining space with some good crockery like plates or tea sets which can be used for occasions as well. On the wall in the living space you could keep either traditional or modern show pieces.

Lighting plays a huge part in adding depth and warmth to a bedroom. I see that you have a light point just above your bed. Without too much expense you can create panelling up to the ceiling , run the wires behind it, and maybe and add a simple false ceiling along the length of that wall to install recessed lighting. A skilled carpenter can modify the head board and create a dramatic taller tufted headboard within the panelling Another option would be to paint the wall behind the bed and add a simple shelf above. Some recessed lights can be added to light up paintings on the wall just above the bed. The homeowners of the bedroom shown here already had a bed which they did not want to dispose of or modify. So all we did was to add painted pinewood box panelling up to 4 feet height, add a shallow display shelf on it, and add a simple shelf above with recessed lights
