That's really very nice! I tried some similar things on a recent project, but gave up on the featured content gallery when I found that it would not play nice with next gen gallery; I guess it never occurred to me to just not use next gen on the homepage. The "like this theme" image or link appears broken to me; the only real question I would have is about listing your active plugins. I'm certainly no authority on security issues, but it seems I recall reading somewhere that it was a bad idea to name the plugins in use, as it might provide a head start for would-be troublemakers; surely you don't want to advertise that akismet spam protection is inactive. Again, I'm no security guru so take that for what it's worth.
Site is really nice looking and well organized.
