This is a very cool room. I love how you've combined spooky with cozy, and that's not easy to do. I think you've done a really good job of choosing artwork that is intriguing and curious but not scary or repulsive, and I like the way you've arranged it, too.
And I noticed you have a light hanging above your bed - if you should happen to be on the lookout for wall-mounted reading lights, here are a couple.
I've got a plug-in wall mounted light just above my bed and love it, it's perfect for reading in bed. But mine is plain white and wouldn't suit the spooky vibe at all!
