Hi jsgrise, yeap, a really wonderful setup you've got there. Congratulations for your hard and esthetic work! On a separate note, thanks also for the very good quality photos!
After taking a close scrutiny, please allow me some thoughts and comments as follows:
1. If you still have a chance you may consider to tilt the center speaker a tad bit downwards to face the main listening position at seated ear height (just like the way you toed in the front towers). Due to directionality issues this will serve to improve audiability of dialogs in your system.
2. It is always a good idea not to put the sofa against the back wall but leave a certain depth, this can take care of sitting out of unwanted standing wave nulls and peaks that occur in any room at their resonanse frequencies. Well done here.
3. This nice front wall suggests the idea for the future to install a projector with a screen as wide as it can get. Ever thought of it? I bet you did!
4. You might have had your well established considerations for a dual sub setup in this given sized room. Care to share? Seems a bit overkill, but just curious.
5. Lastly, some cables visible at the right side give a bit of a distraction for the viewers eyes, you may have some homework to take care of that phenomenon. While youre at it, you may want to look here http://www.lacrossetechnology.com/rs204/index.php
