New house /love/dilemma

Note: I am not a decorator. I have a crazy style and I have a hard time conforming to the way things should be done. I love weird pieces -bright colors- and mix match furniture. I like to use common things in strange ways and well-I like for my guest to say-"it's comfortable here". So with all that in mind-let me introduce you to the big room.

This is the main area upstairs-we have a huge open floor here with this living area (with fire place )

Tons of windows and it adjoins the kitchen and dining area. This room alone is 20.3 feet long. 

And the ceiling is really high up there! 

So over the next few weeks this is project 2 (after the dining room) any ideas are appreciated!
