Project: Rooftop is a really cool site that features contests of Superhero costume re-design.
Project Rooftop = Project Runway, get it! : )

This is my submission for their most recent contest "Canary on a Catwalk" where we were to re-design the costume of DC comics' Black Canary.
Here is a link to the Black Canary wikipedia entry: http://en.wikipedia.org/wiki/Black_Canary
Unfortunately I didn't win, but this was a lot of fun. I will continue trying. I believe a Captain America re-design is next. I'm already working on it!
