Without seeing her room it's impossible to say for sure, but they do pair nicely together.
AINA Bleached Panels
RITVA Brown Panels

Thanks for linking the photos of panels for me.
I can only post a photo from the real estate company when buying so that is not her furniture.
The walls will be painted. The white Ikea cupboards have been moved to another room.
They tried their bed on all walls and the best seems to be coming down from the red wall with the white lace framed mirror on it.Then they have a bedside table on each side and that pretty much takes up the whole wall because they had to leave room for the door opening.
They then have an Ikea birch venneer long dresser on the wall to the right of door opening and a ikea birch tall dress to the left of cupboard door with a poang chair from Ikea in the corner between these dressers.
Now the window wall is where we want advice. The wood canapy will be removed. Her one new item is a solid ice blue duvet cover and shams. She is thinking of painting room milk chocolate or a little lighter. Do we put panels on either side and leave the middle with nothing but maybe blinds on windows themselves or do we put sheers in middle.
She has about 16 inches on left of wall before window. If anyone has any ideas, please let me know.

I like the panels you showed, they go well together. I'd use the dark ones extended over the wall and fill the center with the others. Orrrr you could use a wood blind instead of the white curtains. You'd have the advantage of blocking light. I think a tone lighter than milk chocolate would look good. Is the bed black? It would look good spray painted white to unify it all.

yayagal,
No that furniture is from the previous owner.
The only furniture now in room is the Ikea birch veneer dressers that I mention in my post and a bed that will be changed someday when she makes a new headboard. Now it is just a frame and matresses and her new blue duvet cover.
The window casings are all plastic or vinyl and I am not sure how to attach things or else I would like maybe bamboo shades.

Lyban, does the window cornice extend equally on each side above the window? If so what type of rod is being used now because I'm thinking I'd leave the cornice if at all possible. The top allows a shelf for displaying some art or other items.
Also will she be adding any more dark brown in the room?
