Hmm perhaps the latest webtoon contest could be some inspiration? Also some contests that's hosted by non-profit and volunteers around the world, I'm sure I've stumbled upon a few, but I can't pick out any name out of my head
Also I think it'd be good to have some good exposure to general public, because there'll be some motivation for contestants to submit and the readers outside of creator circle discover that there's some great comics that's barely touched around here...
Or maybe, smaller scale contest like monthly, weekly, etc will teaches some lesson...?
I'm sorry that sounds really generic idea and my english has been quite rusty these days...
