Bedroom Make-Over Pt. 2

Before even attempting to spruce up my room with Ikea and thrift store finds, I started my bedroom makeover with the cheapest method of fixing up a room: spacial planning/ re-arranging furniture.

Problems:
1. My bedroom is long and narrow, has one window and a radiator that blocks a prime corner.
2. My bedroom has to function as a place to sleep and work.
3. My bedroom used to be the dining room, attached to the living room. Now, it appears the landlord decided to hammer a piece of sheet rock to divide the two rooms. Words cannot describe how much this annoys me and inflicts me with design agony.

My first order of business was this wall. For some, this would be their last concern (my roommate didn't even notice it till I pointed it out). It drives me bonkers!

• Option 1 - Paint it with black chalkboard paint or cover it in adhesive cork and center my desk underneath it to create a workstation. No-go: This would leave no room for my bed and it would make the main focus of my bedroom an office. 
• Option 2 - Cover it in adhesive mirror tiles, creating a large full length mirror and also doubling the size of my room (ahhh the magic of mirrors). No-go: I realized I don't want to have to see my reflection THAT much. 
• Option 3 - WINNER. Turn it into my headboard! I've decided to wallpaper this monstrosity and center my bed underneath it. 

Ta-Da!

I'm thinking of painting my walls a purple- tinted gray and wallpapering my new headboard in a black and white toile.
