Awesome picture Gabi! i saw this on your tumblr, its a sweet tribute to the end of such a fun series. Thanks for everything Mr Miller. I have to say thank you to you as well Gabi, because if it wasnt for your awesome fanart i never would have known about this series.
Her name is Stephanie Brown. She is close friends with Cassandra, the previous batgirl who read body language. Her series is Batgirl by Brian Q Miller. arguably one of the best series DC had going before this reboot they are doing killed it. I highly recommend you read it, as it is awesome. check this link for more info (warning, link leads to tv tropes. May burn hours of your time)
This is a great tribute to a great series by a great author and great artists about a great character. Thank you for making this. I think it's important that DC see that this book was loved and their decision to cancel it an shove her under the carpet was just wrong.
