Not exactly my style of decor, but very professionally done.
My only concerns would be the rather high and corner placed racking system. I get the feeling that your components and rack are probably much more susceptable to air-borne vibrations in this location than elsewhere.
If you were able to put a plasma tv on the back and use a double-wide low-profile rack, it would look and perhaps sound even better.
But very nice nonetheless.
-IMO
