I think you'll get better advice showing a picture of the space and size of room. Wall and floor color makes a difference. Nice pieces so far! Any colors you like, or looking for a neutral calm space? Do you have any art already?

Yes, and at under the sectional and the end table. It’s not absolutely necessary, but makes things more inviting and comfortable. Your table is much too close to the sofa, and really not the right one. Maybe a small round one.

Thanks for all the advice! I think I am on the side of getting a rug. The more time I have spent looking at the room today has made it more obvious. Thanks for the pictures Beth, super helpful! I am an extremely particular person, especially when it come to rugs haha (I spent 3 or 4 weeks constantly/obsessively searching for the one in our living room). It is nice to have a jumping off point. Let the search begin... I have a black rectangular planter coming that I was planning on placing on the table and planting some low succulents in (picture). I thought that the table needed something black on it to pull in the light fixture more effectively. I was also planning on putting large plant in the corner. I'm not sure what type of art to put on the wall under the window. The window placement is...awkward. I wonder if a live/moss planting would work? There will be more mini projects and questions that come up for this main area as we move through it. We have most of the major pieces but are missing a lot of the smaller elements to tie it all together.

Ahh, ok, maybe a rug with a more modern feel and black? This is a fairly new Loloi rug, I really like the colors and texture, and sort of sophisticated vintage contemporary feel: https://www.rugs-direct.com/Details/LoloiRugs-Prescott-PRE02/143582/231324 Going more modern, this is a good-looking Surya rug: https://www.rugs-direct.com/Details/Surya-Brooklyn-26206/143542/230957 . It’s hard to say, though, without knowing your decor style. .
