I would choose your bedding and let that decide wall colors and accents.

Here are some photos that may help you. You have the ceiling height to have a nice heavy rod just above the top of you window that could run the ceiling width. That will give you the space to draw curtains back to expose the entire window. I highly suggest that you work with a designer. A good designer has access to literally thousands of fabric choices and will be able to help you in selecting the perfect fabric and design for your room.

your choice of furniture pallet is realy beautiful.
