My Toph's Breakaway amv uses the song Breakaway by Kelly Clarkson. This is the first amv I ever created and I didn't know how to use animated clips at the time, so it is simply a slideshow. I used only The Blind Bandit episode, as I felt the need to challenge myself.

Just as a warning, my Forgiven video has major spoilers for Oban Star-Racers. It uses the song Forgiven by Within Temptation. I've been working on it for the past couple of nights, when I've been too tired to write but not tired enough to go to sleep. Basically, this video centers on Eva Wei, and her relationship with her father and her mother, and how her life fell apart.
Since I can't get it to upload anywhere else: http://www.megaupload.com/?d=CVF4EVIW
