Building Queen Headboard How To Decorate A Bedroom Around A Captain's Bed?

How to decorate a bedroom around a captain's bed? - building queen headboard

Recently moved into a new house, and I would finally like to decorate the room. It's nice and spacious and the furniture that we are currently in the master bed is a queen, that my husband built. It's pretty nice (ok, I'm not mad, but my husband has a lot of sweat and tears in bed and put there for a long time), and wood is a beautiful natural cherry. My problem is that the landscape so BOXY (both in bed and shelves) in the header - I do not know what to do with it. No idea how to decorate the room?
