I don't have time to write a full summary, but I did just upload a few of my pictures. If you're interested, take a look at my Anime Expo 2006 photoset on Flickr. You can see a slideshow here, though you have to click on each picture during the slideshow if you want to see the captions (which might help explain a few things).
Cosplayer of Sakura, from Card Captor Sakura
[Update July 5, 2006: I've added more pictures to the photoset.]
