Hi, what a great news for me!! Thank you for choose my design as the winner.
As for the next step, I think you should wait for the contest to end. I've heard that CH can ended the contest earlier but have no idea how to do that. I guess the instruction should be somewhere in your contest page. And one thing, as far as I know, you need to choose the top 3 winner design from 3 different designer.
If you are not sure about what you should do, you can visit

Thank you very much Manuel!! :)
