Def not the mirror which is only reflecting the ceiling,. Mirrors must reflect something beautiful or interesting to get my vote as decor items. Really can't see much - can you open windows, turn on all lights and use a camera instead of a cell (I'm guessing due to quality.) Please post here and not on another thread. THanks.

I would personally consider some sort of photography to the left and right at about the same height as the mantel itself. Not as large as the mirror, but also with a "landscape" format. While I have photos on here that I link to of my own I'd suggest looking for work by someone local to wherever you are.
