It's a traditional trademark that I've taken quite the likeness to since my first day on this forum. Before I said it held many different concepts of symbolism, none exist currently. It's a reminder and measure of all the mistakes I've made here and in an effort to further self progression the avatar serves to remind me of all my learning experience on this forum.
I chose a broken mask for my avatar partly because it has a sinister look to it, which matches the darkness of my mind and partly because I thought it was a good representation of how I present myself. Not as a broken person, but as someone who has a hidden, secretive side.
