Do a left click on my name, & click ideabooks, click on accent chairs. I have a large selection under $300.00. Wow, I got dizzy looking at the rug.

It looks like you need some window coverings in the high windows. Ikea has some pleated shades you can cut down to fit & even place them vertically within the window casings. Check them out they are ccccccccccchhhhhhhhheeeeeeeaaaaaaaaappppppppp!!!!

Wow. That's a lot of interesting stuff you have there!
Is the television opposite the sofa? My first thought, was that it was...
If that is the case, I guess you want the sofa facing that way so you can watch?
My first thought was to keep the coffee table petite, and put two armchairs opposite the sofa...but only after you pull the sofa away from those windows a bit to balance out the room.
It would impair television viewing, perhaps...so perhaps an alternative is a small square coffee table, lose the red ottoman, pull the sofa away from the windows, and put two apartment-size club chairs centered relative to the fireplace, perpendicular Tito the sofa, with a narrow table between them...
There is honestly so much there, I got a little distracted.
