Hi!
I see you extended the contest. Most entries arrive the last day of any contest. Most designers always upload their versions the last minutes to avoid copy cats, so extending is not a solution but providing feedback. It will happen again, I mean for the next 3 days you won´t receive many new entries. Only the last day.
Here you have a link you´ll also find helpful:

Thanks for your time.
