My first cosplay costume - the Red Pyro from the game Team Fortress 2. Some parts were built from scratch while other parts were off the shelf peices that I just modified slightly. It may not be 100% accurate but I think it came out quite well.
This was created for the May 2012 London MCM Expo which I attended on the Saturday. Unfortunately we had a bit of a heatwave that day so this was not the most comfortable thing to be wearing - but at least it stopped me getting sunburn.
