I love the theme, and we want a library of themes, and in (I hope) 5.3, when the theme-manager for openacs becomes available, we'll have a common set of css definitions for packages so we can apply themes to the toolkit at large that will work with .LRN, too (or vice-versa).
My only negative comment about the page isn't the theme, but rather the large size of the header, which requires me to scroll to see my stuff. The pencil graphic and name and logo don't really add anything for the user that makes it worth forcing them to scroll ...
