Tom’s behind the scenes notes:
This is Sutie, cosplaying as Tsumugi from K-on! It was pretty dark by the time we started taking these photos, so it all had to be artificially lit like this. She had a friend with her who was cosplaying as Mio from the same series, and they were both very nice and very easy to work with. You can see the photos of them together in the Flickr set.
