Help me design this space!

Here is my idea so far....

Anyway, I was thinking a long floating shelf from Ikea above & two candle sconces on either side. I feel like the TV is too high up on the wall to put a rectangular piece of art; also, I don't have a fireplace/mantel and I kind of like the idea of adding a shelf to possible put vases or art in frames or photos.

Here is my digital layout! Crude, I know, but I think it does the job...
