Because of the Lucite or glass look of your chandelier you might consider Lucite chairs as well and I think this table style would look great with your settee

I would avoid anymore tufting. There is enough now with the sofa, the long tufted bench and banquette. Not sure where this banquette is but you could also wallpaper the wall. A gallery wall of pictures or even a glam mirror like below would be fitting of your style. The table and chairs in the first picture are a bit too distressed for my liking but a more refined oval back chair would also look lovely with your set.
