Hey everyone, I'd totally like some advice or insight on what I can do with one particular wall in my house.

It's a north facing wall, with a huge window, I'm kind of at a loss as to how to decorate it with furniture or pictures or anything really. Any help would be greatly appreciated. Sorry the one photo is so dark, the lighting is just so crap and I couldn't get a better photo. Also, sorry for the clutter, I just took down our xmas tree and don't know what to do with a few things until I figure out what to do with the room. THANKS!

North wall that I'm so stumped by:

Other side of the room (lighting is much better, but a little cluttered! (Sorry!)

Don't even get me started on the mantle! It's a disaster!
