Hang a curtain rod draped with sheer curtains (or fabric) at headboard height, behind the bed, then add some white holiday lights behind the fabric and across the rod, this adds a soft, relaxing feel to any bedroom.
Again, I think I would want to go darker on the walls... The white trim, ceiling, canopy, bedding and light carpet and bright windows will help balance dark walls and furniture. I think I'm gonna do it!!
