I would start out with a large, beautiful rug in warm colors (terracotta or red Oriental rug mixed with other colors. I feel sectionals often confine you in how to organize your room. I would choose a fabric couch in a neutral, not too dark color (not gray, which is on its way out and not a warm color), and add two chairs in a different color or at least a different material and style. Try to keep the height of these pieces similar. Two end tables in wood (they don't have to be the same, but make sure the heights are fairly similar and a metal and glass coffee table would look great, with table lamps or floor lamps even if you have overhead lighting, which is always harsh. Pick colors from the rug for pillows and you'll have a beautifully coordinated living space. Books, good paintings and some tall plants will add warmth and personality to your room. People too often don't add these elements and then wonder why their rooms look bare and cold. This may be more colorful than you want to go. and this is a small rug because there is carpeting underneath, but it gives you the idea of neutral furniture and how it can be made more lively with accessories, pillows, coffee table styling etc.

Really nice room, well put together, too. Doesn't seem odd at all -- not even odd shaped. But then, I do like bay windows and I'm liking all that natural light. Like the rug. Like the art (3) on the wall behind/over the sofa … but ... maybe not where it is currently hung as it is currently hung though. Do you have a fourth, similar pic that you could have framed with the same frame and hang them in a (slightly longer) row -- sofa edge to sofa edge -- and hang them lower? Unless everyone in your family is really tall, the art seems hung a bit high. The dark art over the loveseat seems out of place. If you put a tall thin lamp atop your bookcase, you could hang that darker piece to the right of the lamp shade (with the tops of lamp shade and art approximately even). In the single window above where the sofa and love seat form a corner, have you considered adding a stained glass window hanging there? https://www.google.com/search?tbm=isch&sa=1&ei=doMtW4DMO5LcswXLnJvwDw&q=stained+glass+window+hanging+square+or+rectangle&oq=stained+glass+window+hanging+square+or+rectangle&gs_l=img.3...2178.3980.0.4244.13.13.0.0.0.0.147.918.9j2.11.0....0...1c.1.64.img..2.0.0....0.h4yPZoUPbdw You mentioned the shape of your living room -- did that influence your putting the table/chairs by the bay window or, is that your usual/only dining area? If the table is actually used -- perhaps for card games or board games or putting together jigsaw puzzles or for arts and crafts or socializing -- if there is any reason the table is there, then it works there. If you just put it there because you didn't know what else to put in that space, perhaps it is time to rethink its location. Try the rug underneath the 3-seat sofa with its edge stopping at the left edge of the loveseat (after you move the loveseat to the right to center it with the wall behind it). Leave the sofa within a few inches of the wall -- embrace the extra room, especially if that is a fireplace hearth across from the sofa (potential stumble hazard). If it is slightly raised hearth (not just a rug or mat), then make sure you set something on each end so it is less of a stumble hazard: fireplace tools, basket … anything that says "look" so a raised edge hearth can be seen. Prefer taller lamps for living rooms -- leaving the shorter ones with tiny shades for desks or bedrooms. Matter of personal taste, though. Is the interesting tall white fabric rectangle to the right of the piano a cover for a tall ?something? handle or is it a lamp? … Do wait for your husband to move the heavy sofa and loveseat; however, you could work on that corner where thy meet: If it IS a lamp, have you tried setting in that corner where the sofa and love seat meet, either on the floor or atop the short table?

I would move the desk to face entry with some art above. Sofa in front of window with 2 chairs across from it, a coffee table between. Facing the fp, if you wanted add’l seating you can look for an upholstered bench which will keep things feeling open when you walk in. Flank the fp with 2 consoles or small chests if you need storage. Place lamps around the room for lots of ambient light
