You did a good thing by creating the contest. You shouldn't let a lack of participation slow you down. I would recommend taking the time to reflect on what you feel went wrong and how you could change it, if necessary, in your next endeavor.

Yeah of course, I'll try to contemplate whether I should continue making contests or not. I'll try to think of what rules I'd change if I were to continue making contests, but yeah I'd never change about the wording minimum.

One thing I did notice was multiple photo contests that may have conflicted with your own. It could have been that this niche was just saturated. I don't have the data to back this opinion up though.

I saw that there were some photo contests at POB, and that wouldn't be a problem for me. Because I love to see them trying to make POB a thriving platform, but what I see is that the description is too short. But yeah it's about the topic of photography, so a short description won't be a problem. Sorry I don't really understand about it
