How about putting your love seat in front of the window, centered. On the wall where you have the love seat now, but your couch. I think I would put your TV under the pass-through....not in the corner. May need a longer lower stand to put under it. Will be easier to watch there. Then put your armless chair at the end of the love seat cornered toward the rest of the conversation/tv area. Then put your lamps/tables/coffee table in the right spots. I would rethink the sectional....seems like you could have more and better arrangements with two pieces instead of one. Your room looks nice and comfy. Find another accent color you like...coral, yellow, teal, black....any of those would work...and when you get your new upholstered furniture, keep in mind that they should be neutral....I love the color you have now.
