I just posted some pics of our painted brick wall/fp on the fp makeover thread--maybe they will inspire you to paint your brick (or convince you not to! LOL)......

I also think it looks very nice and that you did a great job. I would suggest colorful paintings in your room which will take the focus off fireplace, but mostly it will put some life and personality in from what I can see is a very neutral and decorator-type scheme. Your walls are very dark, although possibly it's just the lighting in this photo, but a few large canvases of art that you love would be lovely.

From Wikipedia. Popcorn was used pre-1970s and in early formulations, it often contained white asbestos fibers. When asbestos was banned in ceiling treatments by the Clean Air Act in the United States,[1] popcorn ceilings fell out of favor in much of the country. However, in order to minimize economic hardship to suppliers and installers, existing inventories of asbestos-bearing texturing materials were exempt from the ban, so it is possible to find asbestos in popcorn ceilings that were applied through the 1980s.

It doesn't look "blue" to me but true white is a cool tone, you have trim that looks to be in the yellow family and the walls I can't tell if they're yellow or green toned on my laptop. It also looks very top heavy with the fireplace being so much lighter and all the trim and cut outs in your wall. Are you or your husband good with woodworking? If it's in the budget and you're willing to put in the work I think doing a more craftman style fireplace would look nice in either a light oak or cream colored.
