Hi Tiffany, here is a link from lowes.com on painting a FP. Looking at your ideabook, I think this is more of the look you are trying to achieve.

I also think you need something more colourful and larger above FP, and wall colour is dark, but would love too see more pics of room and furniture before making further suggestions. Hope this helps!
