I think the challenge is a great idea and good to get the community talking.
One thing - It was said that we were able to cast 2 votes,l which I did, but thinking on it later, these were effectively 2 first preferences, unless the voting thread system has some way of differentiating which vote was 1st and 2nd and preference them accordingly. Somehow , I doubt that.

In that case maybe we should just have 1 vote each.
All the photos entered were great, difficult to choose from and enjoyable to see !!!
