It is a stunning fireplace that just needs a bit of a revamp to match your design style. Consider adding a large canvas of your favorite artwork where the clock is or a family photo! In addition you could use some Mid-Century Modern touches such as this Wall Clock or this Chair & Ottoman could be placed next to the fireplace.

I would also remove the traditional candlesticks & replace with modern. Contemporary figurines would also look good on the two shelves.
