I am good with the framed pieces but not the candle sticks.

Love the start of this room! It does need a few elements. If your not going to dress the radiator with a proper cover, I would paint it silver. The candlesticks are nice, but it's an opportunity to do something really WOW, like wall sconces. If applicable, a rug would be great. Good luck!

I was about to get a rad cover made but got cold feet as I thought it looked so huge covered....and it seemed so much neater just as is with just a floating shelf above..maybe I should re think that.Which style would suit best?

to me, I would go with chocolate chairs or red. I would put a orange vase on table if go with brown chairs or a silver vase if go with red chairs. also on that tray i would add a little yellow or shiny accessory, i would put a brown shelf on top of radiator.

I just did a quick mock up. Great room, but I think it needed a rich colored wall to show off all the cool tones in your design. I also felt switching the prints balance a little better, and the candlesticks would look nice in wood, black, and metal..............Really nice room! I love the martini bar!
