Love, love, love chandeliers when they are used tastefully. Have used them in conjunction with coastal/country style home, timber floors and dados, huge recycled timber table to seat twelve (casual form or bench seats) with two crystal chandeliers above. What is not timber, is painted off white. The living room is again timber and off white, with white leather furniture, open fire place and a huge central crystal chandelier.......but certainly not formal.

Your scheme is very Deco like, the cornice is I'am finding the window treatment too heavy perhaps change to a lighter colour of light beige or white as per photo Colour scheme at the moment is black white and silver it needs a bit of lightening up to add some warmth but I can see Ghost dining chairs really working in your dining room but I think you mentioned keeping the current furniture cheers

A glass dinning table with dark timber legs in a X cross look in the middle of table will be ideal . You can still see the beautiful floor tiles and the dark timber legs will look amazing over the grey tiles. Have full fabric greyish brown chairs with same leg as the table.
