I understand that the outlet's on your radar, and you zero in on it every time you look at the fireplace ... but when I read your post, I actually thought, "Outlet? What outlet?" And I had to look back to verify that an outlet was actually part of the picture. So don't assume that other people are noticing this! I agree with the poster who says that your art is sort of "lost" in the grand scheme of things; it's all about the color. I suspect, however, this art is a great backdrop for something else. I vote for something like RED flowers or candles, something to introduce some color to this monochrome fireplace. I also don't love the grey walls. The fireplace is beige ... and grey doesn't really play all that nicely with it. I suggest you try a real color, not a neutral. Blue is "safe", but you'd need the right blue.

Charley, I would paint the wall the Moccasin as others suggested. Pretty color BTW! I just pulled out the BM color deck to look at it. Why don't you paint the trim and fireplace the lighter shade on the card - mohair? Another option would be to choose a darker color from the card for the fireplace like baked cumin or gingersnaps. If you do this, then everything will definitely blend! Even if you do the fireplace darker, I would stick to a lighter moulding color but not stark white.

Something needs to be on the bench on the right of the fireplace, perhaps a big, tall, and leafy pot plant?

It would be best if you took everything off the hearth below and moved them where they don’t look they could catch fire. I would take away the objects on the right side of the mantle, and I would add a tall blue vase between the madonna and the painting, with dried grasses In it I think I would propably leave the rest of the mantle blank, unless I was going to add St Francis on the other side and a few birds… ;) I might frame and mat the painting and actually hang it.
