The sofa seems kind of faraway from the window/slider to get a good view of the outside especially with the table there. Post a picture of the 4th wall?? I think you should get the layout right before tables, etc

Some layout pics. It is an open kitchen living room type space. Below pics are before we moved any furniture in...

I find coffee tables to be a huge waste of space and hardly ever used. I much prefer tiny side tables at each end of each seating unit. Another problem with coffee tables is that if they have sharp corners, I'm certainly going to run into them and get nice big bruises on my legs! If you insist on having a middle coffee table, get a round upholstered ottoman and put a large tray on it for drinks and remotes. It can double as seating if you have guests. Regarding lighting, ceiling lights don't do anyone any favors in the living room. Much better (to start off with) is a table lamp or wall sconce in each corner at chest height. Lighting is very important for atmosphere. Please give it the respect that it deserves. For wall decor, look for a local artist, art gallery, or some colleges have their own art museums. Art is very personal. Take your time and get pieces you really love. If you don't get anywhere with my first sugegstions, try art.com. Get a print from them and get it framed locally in plexiglass (lighter and safer than glass) where you live.

Your wall hung items are all hung too high. Center them 5' above the floor or hang 5" above a piece of furniture. the trio need to be closer together to read as a unit. Additional, soft accent lighting can be achieved by using lighting on the floor under your plants. Gather them together around an uplight to cast their shadows on the ceiling. Art hung 5" above the sofa can also have an art lamp on it. I would flip the other sofa to this side of the room and push everything toward the window at the end. Put the TV against the wall behind it and set it on a swivel base or wall mount it on an articulated arm. You only need a place for every seated person to put down their drink, etc. Try four "C" tables, one at each arm of the seating. They are light enough to be pulled around for laptops or snacks too. I would rather have open floor space where the coffee table is. Can you afford a new, larger rug. Try placement like the middle one below. Yours might work better in the bedroom.

Add up lights on floor by plants, corners, entry into room. Narrow floor lamp with small glass shade behind tv.

It looks like you might be able to place TV/console where the loveseat currently is (between the lamp and Christmas tree). Then place the loveseat facing the TV on the rug. You also might be able to trade out the coffee table for something smaller and circular. Here are some ideas from our designs included below. Please note the coffee tables and artwork, along with rugs.
