Thanks OP and Congrats to all winners.
As per the issue of plagiarism/using licensed premade vectors by the winners, I think its up to OP if he will accept it or not.
I am not just sure if this would make sense, in case OP don't like that their logo came from licensed vector sources - maybe we can give him a day or two to have every submission be checked whether it is original or not and do another deliberation after disqualifying all plagiarized works.
