I'm no professional, but I'm sure many of them would probably try to persuade you to move the TV on the wall space to the left of the fireplace, and to put something else over the fireplace itself. The media console table that you have in the space is entirely too small for your area (even if you leave the TV over the mantle). It should be higher, wider and balanced with something else on the left side of the fireplace. My first thought is to remove the cross and the diamond and replace with an item of more "presence".
