Re-arranged Room Sounds Awful...How to Improve?

You can click on my system below to see the old set up and the new setup of my room. My old setup was the only arrangement my system had ever known, and I didn't even realize how good it was until everything got rearranged. Now my imaging is all but gone, and a chunk has been taken out of the midrange.

Current constraints:

1.) The setup has to remain basically the same because of the girlfriend.

2.) Room treatments are limited to things that are aesthetically pleasing (yes, because of the girlfriend).

I need help with creative solutions! The room dimensions are listed in the pictures of my system, the ceilings are 10 feet high, the floor is hardwood, and there is a canvas curtain in front of the bay window. The bookshelf is full of books (which helps), and the couch and chair with the ottoman are leather (which doesn't help).

I'm open to anything that you think might bring back some of the musical characteristics that were lost.
