I might add a table (with a lamp) between the 2 barrel chairs and a large rug to anchor the 2 couches. Then I would decide what size cocktail table on top of the rug.

What is the door for? Is it used? Is it the main entrance?

If so, you need to make a traffic pattern for ingress and egress.

Move the love seat to in front of the window. You may not have enough roofer the chairs.

Add draperies, add a bright print. add a coffee table that the sofa and love seat can use. Put a table in the corner so the sofa and love seat can use. Add lamps.

chlerygirls mock up is good, but there is no way to use the door. Put the love seat where the chairs are.

I would make a gorgeous, large rug the first priority. You need color in this room and the rug is the best place to begin, and you can then add pillows and accessories that harmonize. A glass and metal coffee table will allow the rug to show. Side tables (that are different from the coffee table, and they don't have to match each other) with lamps would be next. Great art that is personal to you on the walls.

Can everything slide down closer to the camera so the door can open behind the chairs?

Then you need rug, tables, lamps, art.

I can see you really want a cowhide...
