This is a help...it seems to me that the most effective way to enhance the space would be to paint the recessed wall in a slightly darker shade..adding a little architectural accent...no shelves ...but definitely treating each section differently...pull the couch away from the wall a little... if possible center the couch on the wall change and use similar art pieces centered on each side of the couch...choosing art to go with each wall color but matching in size and similar in style...hang rectangular shape art vertically with top of art not too much higher than top of tv...this will enhance the higher ceiling ...add to a roomier feel in the room....the monochromatic color scheme will also add to the spaciousness..by not stopping the eye on every feature in the room...if you are a little more adventurous ...a bigger...more colorful rug ...and the recessed wall in a color from the rug...will bring a little more life and excitement to the space

This is the only wall I see large enough to support a table and mirror. I'd recommend a Demilune table for this small area. The issue will be selecting something that isn't too wide for the wall area.

Thank you for the additional pictures. I'm going to make a list of suggestions for the entire space for you to think about as budget allows. It's a lovely room with lots of space, but it's not warm and inviting yet. --I agree with Jan that you need a deep wide piece for your child's books and toys. The piece you're showing is too small. If you must keep it, then move it over and put a chair in the corner, lamp to the left. --Or get a very wide wide bench with lift-up storage. Then move your console to the right of your fireplace for your TV instead of over the fireplace. Replace camel sofa with chair. This is very country, but I'm showing how you could put a long bench there with baskets below for toy storage. Great place for guests to sit when you're entertaining. --Next up: Move your sofa at least a foot away from the window, a foot or more back to give the room some airiness. Everything is jammed too far forward there. --Get bamboo shades in a camel color like to add some color at the window with white curtains to the side. These will give texture to the room. --Get a very large rug in this palette that ties together dark flooring, white sofa, camel sofa, and a new color. Here are the colors to look for. The rug should be big enough for all your upholstered pieces to rest on it. Order the smallest rug to try out colors and material. If they work, send back small rug and get large one. This color scheme would work very well in your room, though it doesn't have to be this rug particularly. There's a lot of contrast and echoes floor, camel sofa, etc. -- --Think about adding a long, wide runner to create a pathway into your living room: --Do you have to keep the camel sofa? A comfortable arm chair would fit better there. And the TV wouldn't dominate the room so much if you moved it to the right of the fireplace. It could actually go above the piece you're asking about. Then you could put a great piece of art above the fireplace and have art and the TV to look at. --Are those mirrors going to be anchored. They're dangerous with young children around. In any case, you don't need two of them, just one by the window to catch the light with TV to the right over your console. --I see a various items that clutter up the space. Remove all fake plants and little shelves and little tables. A big round coffee table would fit in much betteer with your sofa and nesting tables to pull out as needed as side tables. Finish should echo the floors and kitchen cabinets. If you're keeping current coffee table, then these nesting tables would work: --At some point get a long rectangular dining table in dark wood to echo your cabinets and floors. Your table looks very small.

Triptych seems really choppy to me on that wall. You already have the two door frames cutting into the space. Across from it you have all of the many, many rectangular windows. The room would benefit from one large piece hanging here and breaking through all the vertical rectangles.
