I wanted to post a very well done on this theme. I'm currently working on it as it may end up as my main the colors are just a great touch.
One thing though. When I installed this theme last night it oddly didn't have a new.gif image. Upon investigation I discovered that a directory it's calling for in the theme is missing. hxxp:yoursite/smf/Themes/sitra/images/brown/ [nonactive]english/new.gif. It seems to be missing for all colors. I just added the SMF default themes dir in place. Just a bug report if you hadn't spotted it it yet.
