The crazy folks over at Xbox have decided to have a community contest where you can enter custom created gamer pics to be voted on by the people at large to include on Xbox One. It will definitely allow for a large pooling of artwork from a vast majority of people to hopefully create some unique images for us to proudly display on our gamertags. Anyways i've included the details of what you need, where to upload and the rules of this contest. Also added mine below which will have a vote for link added later since I would love to have this smiley homage of mine to return.
