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.

The rug is the wrong orientation in relation to sectional. Rotate the sectional so the chaise is on the fireplace wall. Or pull the sectional back, center it on the fireplace, and rotate the rug to center on the fireplace. And remove the pieces from in front of the fireplace so the rug can be closer to it. Can you separate the sectional into two pieces facing each other, one under the window and one on the wall -- and rotate the rug down the middle between them. That woud be ideal...you could see more of the rug. And get bold artwork for the long wall that will compliment the bold rug. Go to greatbigcanvas.com ,for a large canvas print..a fun site and reasonable. 60x40 or 48x32. I searched for peach and teal under Abstract and found these: https://www.greatbigcanvas.com/category/abstract-art/?color=382&color=398&shape=1

Balance: I’d skip drapes as a rod a few extra inches above windows won’t affect the ceiling/window effect. The tv is really high for viewing and I’d be bringing it to eye level. If interested and if room allows, can you turn sectional/console so they are facing windows and place tv there and art above fireplace. If keeping as is, add a huge piece of art between windows again to draw the eyes down into room. . Decor: suggest light textured blinds, a floor lamp and side table in corner with new chair to fill that space nicely and as a nod towards coastal, cushions, lamps and art will do the trick.
