Yay!
EDIT ADDITION: Since this was a competition, I don't see the point of awarding any of the contestants who received 0 votes or 1 vote (1 vote is always for one's own entry). So, I'd say that your decision is generous very generous to the contestants, and should therefore be appreciated. Furthermore, I don't see the point of awarding the top 4 "winners", who, to my mind, obviously cheated. The rest is agreeable to me. So, i's a Yay.
I would argue that the users who didn't receive any votes were defrauded the opportunity for a fair contest by the group of "winners", therefore they deserve a piece of the pie too...
