Check how the listing is painted to match the wallpaper. See how the mirror reflects the wallpaper, making the space feel bigger.
Mirrors on wall gives good perspective :-)
Second hand furnishing combined with new things gets a special feeling. The tableau plate with womans face is chosen by owner to represent the tone of what Vinegrette is. That is why the colouring is performed in different green shades and brown.
Buffet for water and coffee, created with different pieces of old furniture. Glassed frame to make the room more depth, and get the feeling of windows.
When there is no good flowerpot one may always use fabric :-D
