I would get a rug

Move the chair next to the lamp table. Another chair on the other side will balance the seating area. All connect with the suggestion of a rug. Then, you can put a small coffee table in front of the sofa. Appears there would still be plenty of room for the traffic pattern. What a nice space!

We could help ourselves. We think you need a focal point in this room. A coffee table would look good in your living room.
why don`t you try some iconic table like Noguchi coffee table?

Love your house…I think I am seeing Greek Revival...

Start with the fireplace…remove that wall decor and save for another space…it is really good, but not for that spot. Instead, move the art wood there.

No end tables/lamps for sofa…do floor lamps with trays, instead.

Small rug in front of sofa, with small coffee table or garden stools.

Your room is very welcoming but has too many mixed accent things distracting it's best impression. JudyG Designs is right, wood art has to go...as do the smaller pictures & baskets, fruit jars should stay in the kitchen, and the shelf also leaves the room. The oil paintings should stay. Tables should be replaced--add a round one in the corner to left of the sofa (keep the wood light in color, perhaps a painted finish taupe or so not stark white) and move your chair there as well. No table to the right side. A patterned area rug would be good with a dark metal and glass table. Delete the white pillows, keep the striped ones. Hang your drapery panels to the ceiling to make them longer and more stylish, add a contrasting band along the bottom hems in a navy or navy pattern. (hint you could use, cut down, some ready made panels just make sure the widths are the same.) Mirror can be rehung on wall above the chair, not too high now. Hang one of the oil paintings above the fireplace (the larger one currently sitting on the floor. For balance with your pretty buffet styled piece, add a small scale etagere (shelf unit) to the left to gracefully display pictures and mementos without cluttering up your new look.
