great advice upthread I'll try to be short, probably repeating several people: -get rid of the white console next to the fireplace/look for smth else instead if you need it there for function -think of other window treatments. curtains? woven blinds? roman shades? any of these will look better. move your sectional a bit from the wall, both to allow room for window treatments and because furniture generally needs at least couple inches to breathe..that wil also make room seem larger -you already purchased the ottoman in the same color and style of the sofa..off white, right? well something different would be better, but it's okay..buy a throw, fold it and put there to break your lines a bit. tray is great too-both for function and beauty. you'll appreciate it when watching this TV -I liked reading how your wife gets her art:) okay..so if there's no real room for other suggestions(I'm also prejudiced against mass produced canvas art..maybe she can be talked into a print instead?..)..put that art there first. Make sure it fits-seems huge?.. Say you go for that a very similar art, you have there-a bit of white, black, brown, indigo blue, fiery yellow white and brown you already have in your room (btw like your furniture) pull your other colors (in pillows and throws and accessories) from that art -deep sophisticated blues, golds. can be metallic accessories (like vases or flower pots?), can be softest fur pillows can be velvet, can be knitted throw. everythhing you buy-make sure it's a different texture..leather is sleek you've got enough of it. Speaking from experience-I also have my fair share of leather:) then look for a big ticket items like curtains and a rug. (or simultaneously..just keep your general scheme in mind). you can decide to make them fairly neutral. repeat the color of the furniture, just different material of course. or go for one vivid deep color but make it a shag rag for example. Don't try to match pattern to art..art has a mind of its own. Look at the room as a whole..what does it ask for? and know yourself of course..say I love many rugs but I don't like to clean them lol. You know whether it's high traffic area, what your habits are, and whether you'll be sad for 5 min if the rug will have spots and then get over it, or will be sad for 5 days. when you buy a side table try, again, to introduce another texture, just different material in this case. maybe wood. maybe ceramics(garden stool?some of these look really modern). every new material you bring creates dimension. Dimension is something you look for when creating spaces. Why? well that what we've used to. Ouside always has it. Even when it's a desert or an ocean. It has depth. we need to recreate it with all sort of ways and means that are availiable to us.. Good luck! will be a cool room edited because of thousand typos..))

Instead of small photos and shelves on such a big wall, I think a "feature" wall of graphic wallpaper or painting design would look fab. Not exactly this print, but something like this. But, to complement your furniture and design style. You can move the current shelves to the other wall for a collage of photo shelves at eye level.

IMO you buy art because you love it not because it “goes “ with the decor. I think one of the giant floral wallpapers would be great on that wall. BTW wood slat blinds and that chandelier do not work together
