Thank you for your entry which I like, however, for some reason it reminds me of the Power Rangers! At first glance I saw a futuristic mask, although I think what you are trying to do is show a person with their arms around the world. If that is what you are trying, please could you do a new version but that is a little funkier and web 2.0 style?
Thank you for your new entries. As I am half Brazilian, I really like this as it reminds me of the Brazilian flag. Unfortunately, it is precisely because of this that I can't use it. But the colours you have chosen are exactly the right ones.
