Gold and Silver Dining Room

This is the first room I did in the house but I'm dragging when it comes to finishing it. The window treatment came with the house. It's a bit traditional for me and I'm planning to replace it in the future; however I like the gold and silver combination as of now. I want to add some type of storage underneath the mirror. Either a wall mounted cabinet like this (mounted horizontally) or a buffet. So many options in the market and I couldn't make up my mind on it. I welcome any ideas!
