Maybe to extend that idea, why don’t we form team like previous contest (one for drawing, writing, etc)? Then people can vote for their favorite drawing, writing, etc individually? First place would get gold; second, silver; third, bronze except it will be points (gold will get 3 pts, silver gets 2 while bronze get 1). After the voting is over, we can total the scores to get the overall winner.
For example, Team #1 got gold for drawing and bronze for writing, but got 0 points for banner set (or whatever); therefore they got 4 points.
I hope that makes sense.
