Small suggestion @theymos, it would be good to create a poll picking the top ten or twenty art works by 22 November 2019 and post it for voting. Through this even the community users can help in choosing the right winner. One who gets the increased number of votes can be rewarded as the winner of the contest.
Maybe I'll do something like that nearer to the end, though designing a voting system to prevent manipulation is difficult.
Just a suggestion sir, pick the top 20 and let them vote for the winner. They can't vote their self, but they must vote someone else work. I hope this one helps 🙂
