Are you open to painting ? The wood trim, romans and swag are all brown. White trim and white wood blinds would brighten things up a bit. What else do you have going on in the room?

Take down the window scarf and put white roman shades starting at the top of your windows.

I also think the scarf needs to go. What is on the other side of the window besides bright light? Do you need to cover the window because of privacy or because it is so bright out there?? I do not like window covers, but in this case I would put something white in the windows...blinds or shades. But not like the drop thing you have already. I like that the top is left open. Do that again.
