A very large mirror sized to go over a future sideboard would look good. A dark frame similar to the one on the mirror over the sofa would have a good balance. No artwork is going to upstage the Ikea circle panels. But black and white graphic prints would look fine, as others have suggested. You can get large black and white prints of your own photos, such as kids' portraits.

you have a big stone wall demanding attention and the rest of the room is a bit meek - so it wins! Remove the dark brown/black elements (they are not helping). You can tone the wall down with wash, but it's your choice. As it is, on a color wheel, white nearby will make it pop; if you use blend colours for accents to take it though (think bronze/copper/autumn leaves) you will unify the space; or go blues (opposites of the strongest tone) for accents to balance. See the size of the stones? That's your cue for art on the other walls. Try to think at least four stones - preferably 6 to 10. If it's smaller than that, it will lose. Definitely replace the hearth if you can. A stone/wood mantel - chunky - to balance might help and break the wall in a good way. Much larger rug with single colour but texture (maybe even shaggy??) would build up a "good" warm/flintstone feel. Needs an oversize coffee table (the current one looks stiff and plain scared ). Rough hewn/recycled/ oversized chest/stone/ copper trim somewhere would all work - something with a bit of patina and edge, but bigger.

I've chosen manufactured sculpted wood flooring for my house here . Chose Dark wood as I have oak cabinets . Most of the oak flooring was way "the same color as the cabinets". In Md, I had natural hickory flooring (that was stained and finished after installation) It was also stained dark, as I had light hickory cabinets. I love the variation of color in hickory wood. Don't know what color would look good with that stone wall, but it's possible to take samples to see which shade would compliment .

Looks great!!! -Angeline, GKB
