I would put a large piece of art over the sectional (like 60% the length of that arm of the couch) and then maybe just a floor lamp behind the recliner on the same wall. Maybe a side table with a small table lamp next to the other recliner? you could have a small print there, to cover the outlet if nothing else, but depends on the lamp.

The shadowboxes are awesome. The shapes replicate the transom window panes so that was a great decision. Have you ever thought of color on one wall?

BTW, you need a big coffee table for people to set down drinks.

Your home is gorgeous! Maybe one of these on the large wall would add some texture and contrast to tie in your beautiful space. :) Here are a few abstract pieces for you to consider..

I would try placing the long side of the sectional with the back in EITHER of the door openings with a sofa table behind for interest from adjoining room.

This appears to be a TV viewing hangout space, so make it cozy and close. Maybe consider the TV on that larger span of wall... I agree with the Navy wall ^

TV wall mounted for a cleaner look. Ambient lighting for TV and conversation

Floor lamps for sure, overhead lighting is too stark.

You have a great start, you just need some finishing touches. Definitely add some lamps. Different levels of lighting warm up a room and the lamp shapes will be a nice contrast to all the horizontal and vertical lines.

Wall decor doesn't have to be art. You can use textiles, murals, maps of place you love, antique signs that have meaning to you (not fake ones from Home Goods), etc.

Go big, lots of small items together often end up looking like visual clutter.

These paper tapestries from Anthro are an easy way to decorate a big wall space.

^ agree with @deegw - those tapestries are a total steal for their size/impact

Yep… put them up with Velcro and whip them off the wall when you get chilly. Haha.

Move the sectional away from the draperies and the recliner out from the corner. The room needs some floor lamps and a larger ottoman or coffee table.

Seems you already a few gallery walls so it might be nice to do simply a large canvas above your sectional. Then accessorize the room..

It's difficult to judge from your photos but if you can, move your TV screen and console flat against the wall instead of at an angle.

can you move the tv from the corner and wall mount to one of those walls? switchen the sofa around?

Or maybe move the TV trays and put the tv on that wall? hard to tell from the photos.

I like Celerys rendition w/the gallery wall and Pauls dark blue accent color.

I also think you need a larger ottoman for a coffee table. diff light/pillows too

diff types of art you could do

agree about moving the sofa off the wall onto the rug. just leave about 6"-12" behind the sofa.

If you like, you could do a very thin sofa table

you can even do one w/an outlet for lights or charging

Make sure the rug is dead center in the room. Pull out the sectional and position it so that the sofa part is in the middle of the wall.

Just as in this photo you have three cushions and then the corner piece. Place art over each of the three cushions. You can fill in that corner with a floor plant or a floor lamp.

If you used one panel on each window, would there be enough room to put the t v on that wall? It would free up that corner.

You could look at some 3D art like below:

Or maybe some art with blue and yellow in it since those seem to be your color choices in this room:

You might consider updating the chandelier and finding some artwork with blue and yellow in it to help bring everything in the room together.
