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.--- maybe just a string of lights over the headboard :)
Make one special photo charms for your pets, compatible with your Pandora bracelets. Such a beautiful bedroom! The soft grayscale of the bedding, the cute pom poms on the covers, and the cool lights are all fantastic. I would love to have this bedroom!
